I don't have any experience with Matrix, but I maybe I should try it once.

I'm not familiar with Rocket Chat either, but if you missed a feature,
I trust your opinion.

I do believe that longer conversations are important. Think of GSOC,
where the same project runs for 5 months or longer. It does make sense
to keep it well-organised.

Zulip offers topics (which they heavily advertise as one of their
"superpowers") which I find to be quite a nice "substitute" for
threads like those in emails. If we pick that one, I would certainly
go for GitHub OAuth and IRC mirror.

I would discard the idea of using Slack. Based on general feedback
that probably leaves the following top candidates?
- Matrix (might work without self-hosting)
- Zulip
- Mattermost

Rainer, you did not answer about whether you would be willing to try
to install / maintain one of those on the server if we wanted to
self-host the chat?

Regarding Matrix: is anyone willing to set up one ("in the cloud") for testing?
