If the new Serf-friendly protocols are developed on trunk, then they
will be shipped with Subversion 1.4. Will we need to worry about
binary compatibility for a library and protocol that is still in the
early stages of development?

Perhaps we should document explicitly that we do not support backwards
compatibility on a binary- or protocol-level for Subversion binaries
compiled using the new "--enable-serf" option?

Cheers,

David
