Well, my previous post did not use the best possible wording. There are two _independent_ claims which I have joined together more than was necessary, and which you have quoted:
1) #5 is an enhancement request
2) it is not wise to trade enhancement and polish requests for regressions for other users
I still think both are true despite your (unnecessary) notes about cruelty. What does matter is how many users (on both sides) are affected, and how severely are they affected.
For the #5 brltty issue, I have no problem with that, because it could probably be done with no affected users on the other side. It should even be possible to install the screenreader stuff (as a GRUB module?) to /boot only for users who need them.
Moreover, for the other problems - whether to see the GRUB menu or not, and whether to do three or two video mode switches during boot, the screenreader users are on "my" side - they would need to get the GRUB menu with sufficient timeout anyway, and the number of mode switches does not matter for them.
What does matter is, that solving the majority of the "Outright bugs" (in fact mostly polish issues) from the list in the original article can lead to inconveniencing users who do not mind one or two mode switches and a few seconds delay in the GRUB menu, but who do mind when they are unable to see what is currently going on in the system, because somebody has decided that it is not "pretty enough", and "might confuse the ordinary users". This is Apple-style approach to UNIX, and I have to say I am not very happy to see Fedora going this way.
