I agree that Matrix is quite complicated. However, adding new features doesn't have to make it that more complicated. I get the impression that it's not that bad as most new features are actually based on existing parts of the protocol. Everything is just based on events in a room. Most 'special' events have a fallback mechanism to text, to insure clients that haven't implemented the event type can still show the information to the user. Replies and stickers make use of this for instance.
