Bug report

I have found no solution to the issue below. Apologies if it has
already been addressed.

What did you do before the bug happened? (Steps to reproduce your issue)

Have an existing git config with rebase = preserve

What did you expect to happen? (Expected behaviour)

Merges to be preserved when rebasing, without a warning about an option I am
not using.

What happened instead? (Actual behaviour)

I received a warning as though I had used the option on the command line:

warning: git rebase --preserve-merges is deprecated. Use
--rebase-merges instead.

I didn't do that, so I can't follow the advice. There appears to be no
alternative config setting for the new option.

What's different between what you expected and what actually happened?

I expected rebase=preserve to now use --rebase-merges instead of
--preserve-merges, or for a new config setting to be made available to use
--rebase-merges. Ideally the first, because the semantics are clear.

Anything else you want to add:
