IMO, "private, use with care." We obviously have to continue to
maintain it for our *own* compatibility purposes, but I do not believe
that we (as a community) have signed up to support the protocol to be
used *outside* of ra_serf/mod_dav_svn.

For example, if somebody writes me an email saying, "I sent a PROPFIND
like <this> to <that> URL, but it didn't work", then I'd say "eh?
you're not using libsvn_ra_serf? bah. go have fun on your own."

Completely agreed, and I don't think anybody has suggested dropping it
for that very reason.

We've given up on *DeltaV*, but not on Class 1 and Class 2 WebDAV.
