I'm going to pull the lever for "no".
The point of choosing C99/POSIX-2001.1 as our support baseline was to
have a cutoff point that is (a) useful for drastically cutting our
complexity-related burdens, and (b) easy to explain and justify - it is
a 16-year-old pair of standards, after all.
I recently threw pre-10.12 versions of Mac OS X off the island for
botching the time primitives. I can think of no good reason for
NetBSD 6 to get an indulgence.
I think being hard-line about that policy choice has been successful
and we should stick to it.
Technical note: Our OS baseline is not quite POSIX-2001.1 - for rather
obvious reasons we require the time primitives from the 2008 revision
as well, and adjtime(2).
