It's clutter because it adds no information value on a short lived branch. If it's a branch that periodically syncs with another it's ok, if you're just basing off current master for a feature branch rebase is the way to go.
I've developed branches against a moving target all the time where the moving target introduced a problem in my code that wouldn't have been found by a simple merge conflict resolution. It's much much easier to find the source of the problem when you have the real history (a merge) instead of a rewritten history (a rebase).
