Well, I don't see how this is different from the custodian case,
except that contributor is not a custodian.

Cherry picking changes the commit id even if there are no conflicts
and can be done only on one commit at a time.
Pulling does not change the commit id, unless there are conflicts.
Rebasing does not change the history of the rebased branch,
unless there are conflicts and it is discouraged among Linux
maintainers on branches intended for pulling.

Probably, it is arbitrary.
Let me make it clear, I'm not arguing that one way is better
then another. I just thought that we are following the Linux
model, as there is no document describing, how this thing
should be done.

I think this is not just about the code, but the patch(es)
(including the commit message and id) as the whole and
the maintainer (custodian) work.

Again, no rule - is kind of rule, but it would be nice to have
a document describing this decision, so less questions will arise.
