I often wish GCC supported it -- not in the hopes of finding every
conceivable bug or transgression against known coding styles but
as a tool to discover warnings that have to be explicitly enabled
either by using their own options or by specifying a higher level
than the default.

I agree that using -Weverything on real code would lead to far too
too much noise to be practical, but I think the concern that it would
cause frustration and lead to complaints and bug reports could be
mitigated by documenting the option's purpose or even by issuing
a warning for using it.
