It seems so.  I wanted to be sure that people understand the
rationale, and not dismiss as "one of those weird Apple things".
Amusingly, one of the other warnings we added turns out to be
identical to the recently-added -Wendif-labels, and I'm glad
not to have to argue about the value of that one!

Well, you did complain about adding switches in general.  I think
it's the wrong thing to complain about, because users generally
consider the wide selection of switchable warnings to be one of
GCC's main strengths.  Have you not ever heard that from users
yourself?
