We could rebase the branch and then rebase the in memory changes on top

hmm, you are right. this may still result in a commit on the branch for the
rebase. it should be possible to avoid it when the rebase is actually a
no-op because there were no changes by other sessions.
I think this is already the case. See
org.apache.jackrabbit.oak.spi.state.AbstractNodeStoreBranch.Persisted#rebase
For the other branch states rebasing is already entirely in memory. I
quickly hacked together a POC patch for above approach. Chetan agreed to
do a quick check with that.
