I’m not sure if Lemmy federates downvotes. ernest has said that kbin doesn’t, though. Maybe that’s changed since he made that statement.
AFAIK, though, there’s no need for changes to ActivityPub. It has everything it needs to propagate ‘actions’, which can be defined however a platform chooses. Other platforms just need to know how to interpret those actions in order to do anything with them, and I don’t see sites that aren’t aping Reddit’s engagement model to care about downvotes in any way.

Upon review you are probably right - there is quite a lot of discussion about it here: https://codeberg.org/Kbin/kbin-core/issues/3
