I would love to have a matrix integration for this service (with the same behaviour as slack or discord for example). There are already open-source bots available like go-neb: https://github.com/matrix-org/go-neb which could be used.
I think that because element.io (a client for matrix) acquired gitter (a chat and networking service for developers), that the amount of developers using matrix will grow rapidly.
This would be nice to have
