I don't think that's true. You do not need to have a remote at all to
use Git.

But more importantly, the commit is not in any way tied to a specific
remote. You might have multiple remotes that are storing many of the
same objects. So even if you wanted to somehow assign a segment of
history to a remote, it is not an unambiguous mapping.

Your second sentence is fundamentally at odds with how Git works and its
decentralized data model.

Sorry, I just don't agree with any of the logic here. That's not how
commits work in Git, and all of the solutions are not equally imperfect.
