Strong disagree: until the branch is merged, it's mine.

I'm in a camp that prefers single rebased commits as units of change, "stacked diffs" style.

GitHub in particular was annoying with this style but is definitely getting better. It's still not great at dealing with actual stacks of diffs, but I can (and do) work around that by keeping the stack locally and only pushing commits that apply directly to the main branch.
