For some reason this hadn't occurred to me before, but I guess that basically every messaging and chat platform nowadays is just a HTTP or WebSocket API? Instead of a custom protocol?
@joepie91@social.pixie.town I'm guessing that the 'Matrix over CoAP w/ CBOR' isn't quite what you mean since it's still at a higher level than the 'transport layer' ? I know that was a demo MSC that hasn't actually entirely panned out (something about needing funding to continue working on it?), but it seems to kinda fit the bill to me otherwise.
@red_sky I mean, I'm sure there are still some things with a custom protocol for some circumstances, but in practice everything (Matrix but also proprietary chat things) is addressable over HTTP now without weird reverse engineering nonsense like used to be necessary for stuff like the MDN protocol
