I think this stuff is too much for most people to use, but Beeper is not missing anything deal breaking. I use it daily and besides being bulky, it has nearly everything one would expect. For most apps, it has their reactions functionality for example.
What’s missing:
The reply mechanism doesn’t work as well as it does for specific apps that are better with this. It does basic reply quoting but that’s all.
Notifications could be better. There’s no customization per type of app. They do all keyword notifications which almost no app does. However since notifications are all or nothing it is just okay.

Overall, the app is super solid and works well. I agree I don’t think it’s perfect and has plenty of bugs or lacks specific nuanced features.
I don’t think we will ever get a common uniting protocol. We never had it. Even when jabber was the common protocol, FBM didn’t support group chats with it.
I am assuming Matrix is the best we will get. Or some other sleeker app building off Matrix will come out. We do have MatterMost too but it seems Matrix “won”
