I'm not sure exactly what you mean; relocate wouldn't need to change it,
just refer to it.
Adding the UUID in the repos gives two major benefits:
1.) it lets the client validate that, barring malevolence, the
repository its URLs point to is the one that was there before
and
2.) it lets clients and servers use UUID/Node/Rev triplets to
uniquely identify the chunks of data that they exchange; this
is an important step in building a distributed repository
scheme.

Yes. This is a very important point, IMO.
