Agreed.

For a complicated long running feature branch I can see it. Instead of repeatedly merging the root in during development it can be cleaner. Tools aren’t always good at figuring out in a PR what was written and what was caused by those merges from root. And history looks better at the end.

For a short branch that can merge cleanly or perhaps very close to it, I’d kind of rather have the ‘true’ history. I don’t think it’s worth it.

I’ve never understood the “everything must be rebased before every merge” desire.
