Yeah, I didn't want to say anything because I'm no expert, but as far as I can tell, Matrix clients use a Rest API. It's not like they are resolving state deltas locally or something. It seems like the big complexity right now is the encryption, since that, by definition, has to happen on the client. There's a concerted effort, however, to make that as easy as possible with shared libraries and such.
