I think they rather ask for avoiding tons of meaningless automatic
merges resulting from periodic pulling from upstream.

Those subset of the above who only do small discrete patches don't do
merges to their tracking branches, except by mistake, right? If so,
'pull --rebase=preserve' makes no difference compared to --rebase=true
to their normal workflow. Moreover,if someone merges something to his
tracking branch by mistake, how is it different from making merge to any
other branch by mistake? Just fix the mistake by resetting to previous

On the other hand, if someone decides to merge something else to his
tracking branch by purpose, both --rebase=preserve and --rebase=false
perform as expected, while --rebase=true may easily lead to huge
surprise. Please refer also to this thread for one such case:

Once again, in case of mistake they are free to use --rebase=true, and
even then using 'git rebase' directly is probably cleaner. That said, I
don't argue --rebase=true could be sometimes useful. It's just that I
think --rebase=preserve is safer, so it should be a good idea to suggest
to use it (in favor of --rebase=true) in general.

It does indeed, and I don't think my aforementioned workflow is too

--rebase=preserve works fine for the aforementioned workflow. At least
simple tests I performed so far ran fine. I'd like to learn though which
nasty drawbacks --rebase=preserve has for tracking branches compared to
--rebase=true, if any.

That would be an improvement anyway, indeed.
