This is a nonsense argument - before anyone would possibly be required
to upgrade their working software because of changes to AXFR that put
something different in the auth/additional sections than what is in
the answer section, all those administrators are going to have upgraded
their software for other reasons anyway (and not necessarily all for the
same one).   What's more, even if a few haven't, it would only matter if
their peer axfr servers actually use whatever new might eventually get
defined.

All that is needed now, or anytime in the forseeable future, is that you
add the one line of code it takes to stop processing at the end of the
answer section, instead of at the end of the packet, and include that in
the distribution.  You don't have to suggest to anyone that they upgrade,
just make a version that works this way available.

Then, long before it is ever going to matter, the thousands of sites
are going to be 10's of sites, at most.   And most of then may never
notice.  And this is all *if* anything is ever defined to use the
other sections.
