Sounds like the only logical option.

How about using warnings::register and putting these messages
into warnings::warnif()? That way I could say

    no warnings 'gtk2-useless';
    # or
    no warnings 'gtk2-deprecated';
    # or even (to get the typical console messages to shut up)
    no warnings 'gtk2-assert';

An obvious advantage is that using pragma gets us lexical scoping
for the warnings at no extra cost:

    if(
        do {
            no warnings 'gtk2-useless';
            Gtk2->get_version_info;
        } == 222
    ) {
        # work around some bug
    }
    else {
        # just do it normally
    }
