I think it could be another gateway for more people to start using matrix, because they don’t need to bother with two apps and wouldn’t need to learn a new UI for matrix.
But maybe also not since it would require another app install anyway.
I guess its not really worth it if maintainance becomes too complicated.
For mobile I also recommend Finamp. It is FOSS and built for Jellyfin, with offline support.
I am using the beta which has more clean UI and is very stable.
