No, we don't need --no-rebase-merges for --rebase-merges-mode to work.
It would be nice, but not necessary.

No, it would not become invalid, that's yet another decision to make.
`--rebase-merges=mode` could become synonymous with `--rebase-merges
--rebase-merges-mode=mode`. A shortcut.

Because it's redundant it could be deprecated in the future, but not
necessarily invalid.

No, `git log -m` was a mistake *only* if -p isn't turned on as well,
which is an interface wart that could be fixed today.

Whether --rebase-merges-mode turns on --rebase-merges by default is a
decision that could be made in the future. Just like `git log -m`
turning on `-p` by default is a decision that could be made in the
future (and probably should).

---

Either way: introducing a new option cannot possibly break backwards
compatibility.

Cheers.
