M:N Ids to Url mappings

[bestia-dev]

I am wondering why is it possible to have more "crev ids" for one repository url?
Is there a need for this? What use case am I not aware of?

An id can change their url and start advertizing new one in new proofs, to allow smooth transition of proof hosting, etc.

Eg. if I moved my proof repo gitlab, I could change my url, publish to both old and new one, and eventually retired the old repo and delete it.

Or at least that's the theory.

Oh, sorry. I've misunderstood. The other way around.

One repository can host multiple ids - people can share a repository (eg. in organization) or have different ids for professional and personal use etc.
