Please don't reduce the issue of "rename tracking" (or whatever you
want to call it) to merging. It's just as relevant for updating (cf.
tree conflicts of "local edit, incoming delete" and "local delete,
incoming edit", etc., which you can just as easily get with a normal
update). When there is proper rename tracking, I fully expect these
kinds of tree conflicts to be resolvable automatically (most of the
time). Whether it's a merge or a regular update.

Unless you consider an update a special kind of merge. However, I
don't think that's the case in the mind of users (at least in my head,
as a user, the two are quite different, I use them in totally
different contexts). That's why I think "Branch-relative renames" is
not such a good term. It couples the rename issue to
branching/merging... It's more than that.

Cheers,
