-w prevents any warnings being printed at all, it couldn't be used to
turn off -Wstandard then selectively re-enable individual options,
e.g. with -Wno-standard -Wmain

Introducing a new switch would mean there's a single -Wno-standard
switch for those who want to restore the old default behaviour, so
they don't have to explicitly add -Wno-aaa -Wno-bbb -Wno-ccc etc.

Maybe -Wstandard isn't the best name though, as "standard" usually
means something quite specific for compilers, and the warning switch
wouldn't have anything to do with standards conformance.
