Yes, but with GCC you can't control the scope.

My point exactly. This confirms that it is preferable, for that
company, to disable some warnings instead of "fixing" them.

This in turn leads to another interesting question: why don't they fix
such warnings anyway? After all, that's what they're asking library
developers to do for them, right? At least in some cases, I'm sure,
the answer is "because that would do more harm than good" (as far as
this particular company is concerned.)

Therefore, if a library developer "fixes" a warning, some companies
would consider that helpful, and some would consider it harmful
(except, of course, companies that put their money where their mouth
is, and never, ever disable any warnings.)
