I'd like to see concrete use cases to support a copied-to implementation.
As stated in another mail in the thread this one has spawn off from,
I've implemented this once for a client, using properties to store the
copied-to info (which isn't a good design but works as a proof-of-concept).
The use case this was going to support was "given fix for a bug, how I can
find out on which branches this fix has been applied to already?".
This use case is invalid IHMO because it can be answered more effectively
by an issue tracker than Subversion itself. The client even ended up not
using the code.

Do you have other use cases that would benefit from having copied-to
information available?

Yes, I think it would. This is one valid, albeit exotic, use case already.
