You bet.

Space savings is good. Rewrite is good. But also note that the table could
include more than just the UUID. We could also include other metadata about
the repository. "Canonical URL" or "Owner" or ...

This is what relational DBs are all about. Enable the relation, and then you
can grow into all kinds of cool stuff.
