as more diverse activitypub software comes into existence, there may come to be more and more cases of instances implementing features that aren't supported on other instances or that aren't expected by generic clients. for instance, awoo.space supports unlimited post length when the post has a CW on it; this works in the client but doesn't (and, as far as i know, can't) work in the Tusky mobile client
i wonder if there's some way around this in general
