This is because they've been in Gnulib since July and several packages based on these Gnulib changes have been released since then. Current Gnulib assumes these changes will appear in the next Autoconf release; if that's not true, we'll need to upgrade Gnulib and in the meantime the other packages released since July would still have the changes whatever we do with Gnulib and/or Autoconf.

The fact it's already shipped in gnulib & that the "real problem" is in glibc IMO means that I don't feel
strongly about reverting it.

You're right that distros have the toggle so as long as we mention this prominently enough in NEWS,
I don't have a strong objection to master being released as-is.
