The concrete problem is that, without the hack I described, we cannot

AC_INIT([bar], [1.0], [foo-bug@[192.0.2.1]])
I doubt whether the latter sort of thing is used much if at all. If someone
needs it, we can suggest that they use AC_INIT([bar], [1.0],
[foo-bug@@<:@192.0.2.1@:>@]), which should work with both old and new Autoconf.
I expect the main problem is more with examples that you mentioned downthread,
like this one from GMP:
AC_INIT(GNU MP, GMP_VERSION, [gmp-b...@gmplib.org, see
https://gmplib.org/manual/Reporting-Bugs.html], gmp)
For this particular case, a simple workaround is to use " -" rather than "," in
the 3rd argument; this should work with both old and new Autoconf. It may be
that requiring this sort of workaround would be better than a hacky
implementation of AC_INIT that attempts to guess what was intended. After all,
GMP's use of AC_INIT doesn't conform to the 2.69 manual, which says that the 3rd
arg should be an email address.
After writing the above it strikes me that there should be a quadrigraph for
",", though of course this won't help in code intended to be portable to 2.69.
