Agree. And adding one for -Wall is especially tedious because you have
to spell out the list of affected warnings in two places :)

Yes, that should be possible.
I feel like maybe we should still have individual settings for the three
different classes, because you might want to have -Wshort-desc without
the extra -Wcontents-before-sections (which I thought about removing
entirely, kernel-doc seems to parse just fine that way, what's the point
of it?)
But we could even move the env var handling _completely_ to the Makefile
if you don't mind, and then we don't have to have two places in the
script that need to be aligned all the time.
