Well, I can hardly refuse a pull that removes almost 200k lines. So
I'd happily pull it. Just this single line in your email is a very
very powerful thing:

However, before I would pull, I'd definitely like to make sure we at
least have some way forward too, and clarify some issues. So I have a
couple of questions:
- is this guaranteed to be a no-op as things stand now, and what are
the secondary effects of it?
Put another way: I realize that fairly late in the -rc series is
actually a really good time to do this, rather than during the merge
window itself when things are in flux. However, while it would be a
good time to pull this for that reason, it's also a _horrible_ time to
pull if it then regresses the defconfig uses, or if it causes horrible
problems for linux-next merging etc.
- what happens when somebody wants to update the defconfig files?
This is a question that involves a number of people, because over
the last half year, we've had lots of people changing them. "git
shortlog -ns" on that ARM config directory gives 39 people in the last
half year, with the top looking roughly like
26 Ben Dooks
10 Tony Lindgren
4 Haojian Zhuang
4 Kukjin Kim
3 Santosh Shilimkar
2 Janusz Krzysztofik
and how are these people going to do their updates going forward
without re-introducing the noise?
IOW, I'd _love_ to get rid of almost 200k lines of noise and your
approach would seem to have the advantage that it's "invisible" to
users. But I would want to get some kind of assurance that it's
practical to do so.
