Sorry, I am turned off by the CRDT in there. It immediately smells of overengineering to me. Not that I believe git is a better database. But why not just SQL?

Merges require revisioning. JSON or SQL do not have that in the model. This variant of CRDT is actually quite minimalistic.

I would argue LWW is the opposite of a merge. It is better to immediately know at the time of writing that there is a conflict. CRDTs either solve or (in this case) don't solve a problem that doesn't really exist, especially for package managers.
