Ranked yes pp and score no that would be too much of a shift for an extreme accuracy meta which a lot of people would hate (especially since we just got a pp rework favoring accuracy players).
Allowing HR without additional score / pp to be ranked is only a good thing to let people try HR out for accuracy training purposes or whatever because there's really no reason it should be unranked, since it would just be the same score calculations as a nomod score vs HR enabled, since all it changes is the judgement window to be smaller anyways.
