I think both are done for long-term forks. Since both are done we can surmise that both are practical.

I suspect that rebase-forks are more common historically. Because the only thing I’ve heard of when it comes to managing changes on top of a version control system (which could be centralized) are “patch queues” or stacks. And those tend to be rebase systems with a different system.

But I have no practical experience with long-lived forks.
