Well, that's not entirely true. With your system, it would be dangerous 
to simply move files into the new repos, because there could suddenly be 
a temporal overlap between the files. There could be several files with 
the same name at the same time, etc. Therefore, you would still need a 
special tool to do this.

With SVN, this is checked by the merge tool, which allows you to rename 
the old repos into /new/branch. Such a tool would be needed for your 
system too.
