Beyond having compatible UIs (which is tough if you're aiming for something relatively universal), there's then the issue of feed management.
The more that's pumped into your feed the more you need to filter and separate it out. That's a big UI challenge fediverse platforms don't seem up to either and which is generally tough. Not to mention that separate platforms or "spaces" actually become a feature here for helping one's feed management, as annoying as all the apps can be.
