Just having `--rev -r` inside the parentheses should be enough, but I'm not sure if implementing every piece of exclusivity logic here makes sense (I'm also concerned about completions diverging from real behavior). But I've found this in zsh's _git:
`(- :)--abort[cancel revert or cherry-pick sequence]`
This form disables completion of any other arguments, and I think it's future-proof enough to do this for `--abort` here. I'll do a follow-up to touch just exclusivity when this series lands.

I don't think it matters. All options that the group mentions just disappear from completion when `-l`, `-m` or `-u` is present.

You mean giving revisions without `-r`? No, `*` means that `-r` can be specified multiple times (and each would require an argument). To see how it's done for a command that has "optional" `-r` see _hg_cmd_update or _hg_cmd_strip above ^
