My Fedoras run SELinux enforcing all the time (since before systemd, in fact). Never seen boot hangs due to this. Never seen LVM related trouble either (but no RAID or encrypted filesystems on any of them).
Yes, I know that the plural of "anecdote" isn't "data," but still.

UNATTRIBUTABLE STORIES are anecdotes. First-hand accounts are datum points. And ignoring datum points is what gets scientists accused of either (a) fabricating evidence or (b) ignoring inconvenient evidence. Either charge if proven is - and should be - fatal to any scientific argument.

On the other hand, not all types of »evidence« are the same. One person claiming they briefly saw something fuzzy in the distance that might have been a Sasquatch is different from one person bringing an actual live Sasquatch in a cage to a convention of field zoologists. It is a lot easier (as well as usually more appropriate, Occam's razor being what it is) to ignore the first than the second.
In the same vein, somebody claiming that they once had some sort of terrible problem with software package X but they don't quite remember the details is different from somebody demonstrating an easily reproducible sequence of steps that reliably makes the current version of software package X crash – especially if the person in question is on record as preferring software package Y which is a direct competitor to X. The latter is evidence but the former is FUD.

Tens of thousands of people with unreproducible pulseaudio problems signify an engineer who designs clever but fragile software for a non-existent perfect world.

Tens of thousands of people with unreproducible Pulseaudio problems eventually lead to those problems becoming reproducible, being traced to buggy ALSA drivers, and being fixed there (rather than in Pulseaudio) as is proper. Pulseaudio is now quite stable.
What would you prefer, Pulseaudio working around the driver bugs? I know what I'd want: a simpler Pulseaudio and less-buggy ALSA drivers, thank you very much.

I can hear you thinking "And this is relevant how?". Well, it serves as an example of how difficult, or at least annoying, it is to have to work around faults in a subsystem that has become too tightly integrated. I have had no problems with systemd myself, but I sympathize with those who worry about the consequences of allowing it to subsume more and more system functions.

"(...) it serves as an example of how difficult, or at least annoying, it is to have to work around faults in a subsystem that has become too tightly integrated. I have had no problems with systemd myself, but I sympathize with those who worry about the consequences of allowing it to subsume more and more system functions." To a desktop user, working sound reproduction is considered a basic necessity, i.e. 'must-have'. To a server admin, sound reproduction might not be considered a basic necessity, but merely 'nice-to-have'. To a desktop user, a working init etc. system is a basic requirement. To a server admin, a working init etc. system is a basic requirement. In other words, a working init system is 'must-have' in both cases. You can probably see where this argument is going: Comparing the two on equal terms is perhaps slightly misleading if only for the fact that there is a bigger group of people who have a vested (commercial) interest in the init system just working. It thus seems reasonable to suggest that, if a problematic edge-case is discovered in systemd, there is likely to be much more pressure to get it fixed ASAP than if PA needs to be restarted every now and again on your box, which (lest we forget) is running a desktop OS which only has a market share of a couple of percent or so if we're being generous. Unless I'm mistaken, the majority of the Internet runs on Linux-based servers? That said, I haven't noticed any issues with PA on my machines in, like, forever; my personal impression is that it tends to "Just Work™" regardless of distribution these days.

The plural of anectdote isn't data, but "tens of thousands" random points of noise aren't terribly useful as data, especially when contrasted against a far greater larger sample set of folks who had a greatly improved experience.
Meanwhile. Speaking as an engineer who designs stuff for the real world, you need reproducible test cases in order to take action, less you break other crap in the process and possibly/probably not solve the original problem. Whatever it may have been.

Yup. But the advantage of a first-hand account is that you can go back and verify it. Okay, you might not be able to repeat it (the sciences of eg biology and astronomy often suffer from this where they can only observe, not experiment), but if you have a reliable witness or account then it is extremely dangerous to ignore it.
At an absolute minimum you need to take it seriously and explain it.
