Fortunately it's being worked on.
I beg to differ with your argument about it not mattering whether a bug is
categorized as a regression: Rafael's regression list is far more prominent
and the bugs listed there get fixed with a high likelhood.
Note that there's clear evidence of that in this very thread: the hang bug
was ignored as a "plain" DRM non-regression bugreport, _despite_ the prior
scrutiny in the thread, up to the moment Linus pointed it out and turned it
into a de-facto regression ...
There's also another purpose of categorizing bugs as regressions: tester
timeliness. We tend to treat bugs as 'plain bugs' when they are reported too
late after a few kernel releases of the bug having been in the wild. We do
this to encourage testers to test earlier -rc's as well, as there's a real
tangible benefit of the 'we dont do regressions' policy: bugs get fixed and
testers feel involved, and it's also the stage were we _can_ fix bugs with a
lower cost to all parties involved.
But what 'timeliness of testing' can there be if new features are added in a
late -rc and bugs are explicitly categorized as 'not a regression'?
