Note that SVN has globally serialized revision numbers (change sets).
Which means that there has to be a chunk of metadata that does the
serializing, and it has to be per tree.

Bitkeeper went down a series of rabbit holes trying to do change sets
and detachable subdirs at the same time. It simply doesn't work. If
you need detachable subdirs, you should create separate 'projects' for
each directory, and accept that there won't be a link between all the
components of a change that touches multiple directories.
