I agree that 11 is nearly dead, but 12 still has a year-plus to go.

Another point that I wasn't thinking of yesterday is that 11 is
still expected to compile on pre-C99 compilers.  I'm not sure
to what extent we are still able to test that -- my old animals
have all gone to buildfarm heaven, although I see that Noah's
AIX menagerie is still soldiering on.  Were we relying on "{ 0 }"
anywhere else pre-v12?
