I believe the requirements for code repositories and the requirements
for document repositories are in some sense incompatible.  Thus, the
client can't count on certain things being true for both kinds of

We may need:
 - "type A" where the client can count on versions being immutable and
version URLs being non-reusable
 - "type B" where the client can count on versions being mutable and
version URLs being readable.

I agree the client needs to be able to count on certain behaviour, but
it will have to be a different kind of behaviour depending on what kind
of server it is talking to.  Otherwise the needs of document-versioning
servers will NOT be met by the versioning draft.
