I'm thinking of the case where a distro packager uses those
configuration settings. Then a downstream sysadmin thinks, "they
guarantee this is safe" and upgrades to the latest svn release. BOOM.

Yes, we can blame the distro packager for screwing around with our
compatibility rules, but I'd rather not give them the choice.

Would you be okay with a --with-apr2 setting that is labeled
"experimental" and issues a warning? ("use of this option is
incompatible with regular Subversion releases") (or maybe the
--with-apr2-experimental or somesuch?)
