No, I mean -- with reference to the levels in diagnostic.def -- controls
along the lines of

    #pragma GCC in this code I'm only intested in errors

    ...

    #pragma GCC in this code I'm only intested in errors and warnings

    ...

    #pragma GCC and now I'm back to normal:  errors, warnings, notes,
        anachronisms, severe weather announcements, specials at the
        local grocery, etc

An analogy for people familiar with sysadmining or daemon programming
might be the syslog-style kind of severity thresholds.  Naturally, that's
not always appropriate for a compiler (ignoring an ICE is just not gonna
happen, as much as we wish we could do so), but -- introducing an opinion
now -- I think there is room for more than two levels (warning or error)
of diagnostic.

However, that all falls under feature rather than requirements.  Just
something to think about.
