For signal, telegram and mattermost, I am not too worried since their protocols are documented. Matrix support is planned and should not be too much of a problem either. About the full-proprietary platforms like messenger and discord that are actively against alternative client implementations, it's probably going to be hard to keep this working by myself. I chose to rely on 3rd party libs for this very reason. But even if these slidge plugins break, I'm still happy to use my XMPP clients for the more or less opened networks.
