The benefits of DAV (such as autoversioning support, browsable
repository URLs via directory GETs, etc.) are not lost by allowing
mod_dav_svn to communicate solely via customer REPORTs when it's a
Subversion client doing the talking.

We could start using custom REPORTs and POSTs for all Subversion
operations, but additionally support the "real" DAV stuff necessary
for those aspects of DAV we care to shoot for. In other words, start
with a working, performant version control system, and then add
cheap(ish) goodies as desired.
