@zaskoda I would respond that #Fediverse is to its core built on identity being coupled to instances, so what you're describing isn't combining with Fediverse at all.
This is related to criticism so many of us have about the technical design that went into #ActivityPub from the beginning. It wasn't built on decentralizing like it could have been.
Sure, it's a step forward and we can recognize that, but meh, it could have been so much better.
@volkris ideally, I would like to see identity decouple from server instances and a native mechanism to allow users to compensate server admins for the cost of running servers.
