I’d really like to add it. The problem is I’m not sure whether to use kind 1/1111 or kind 1222/1244. The first option would show up in most clients, while the second would only be visible in some.

It’s similar to kind 20 picture notes, users get confused about how they differ from regular notes, and why their image notes don’t appear in certain clients. Until I figure out a good way to solve that, I’d rather hold off on implementing it.
