I don’t remember hearing of it till now, yet it claims a lot of desired features. Github page shows only one contributor, one fork, 44 stars; lot of commits in the last week, oldest 3 years ago; GNU Affero General Public Licence v3.0.

Nice, thanks. Though I’m afraid what I/we need, is a FEP for group chats and end-to-end-encryption. (And some kind of reference implementation.)
Shoot uses a variant of FEP-1b12 for group chats, it is the same protocol on which Lemmy communities are built.
However, chats typically require a more fine-grained permission system than Lemmy currently offers. This is what I am working on: FEP-5219: Groups and permissions
>end-to-end-encryption
Not a thing yet.
