If we are, we'll never learn if this code is needed on anything beyond Solaris 8 and keep this cruft around basically forever. I'll at least try a bootstrap with the nframes = 2 code ripped out with Solaris 9 FCS libc and libthread (and of course the whole rest: latest Solaris 9, 10 and 11) and see if anything breaks.
