I was referring to previous posts to this thread.

I mean "configured" but "used" works just as well because that's where
the complexity and maintenance burden comes in. Such properties are
pretty much equivalent to mergeinfo in the sense that they control the
behaviour of the client and server, and would have the same tendency
towards complex edge cases and unexpected usage scenarios.

I've proposed before that we introduce proper branches, and gradually
phase out support for the copy-is-branch paradigm, for example, by not
supporting smart merging between directory copies but only between
branches. There is no good reason to continue to support every feature
we've ever had, assuming we provide a migration path *and* publish a
roadmap so that users can be made aware of such upcoming changes.
