That would circumvent the point of W=1.  Level-1 warnings are deemed,
and I'm paraphrasing/making this up "not worth rejecting pull-requests
over".  In contrast, if Linus catches any W=0 warnings at pull-time,
he will reject the pull-request as 'untested'.

W=1 is defiantly something you'll want to enable locally though, and
subsequently push back on contributors submitting code adding new
ones.
