That you then need an "svn branch" command to differentiate between
ordinary copies and actual branches, because you can't just always
blindly assume that a directory copy is in fact intended to be a branch.

Or even better, first-class branches in the repo. Makes for less user
confusion as to what's tree structure and what's branch structure. What
I've been proposing for years now. :)

P.S.: BTW, this proposal reminds me of the "really simple" idea that was
svn externals, it would "work just fine" until we could get real links
in the repository and such ...
