Linus has been pretty clear about not wanting warning options enabled
without first fixing all the cases it warns about first. If that's
changed, then sure, let's do it; but we went through a lot of coordination
with sfr for linux-next nag-mail coverage (where maintainers are now
fixing it themselves) when this came up during the last kernel summit,
and this approach was the agreed solution.
