I don’t see the big problem in 1. Compare it to e-mail. If you want to switch provider you have to backup and restore your emails if you want to.
Nobody bats an eye that amiladresses contain a maildomain but with Lemmy everyone is used to the reddit way. Give it some time, people will get used to it.
The syncing and federation problems we are experiencing right now will get solved in the future, people will get used to the new naming scheme.
Point 2 is a great idea btw.
Instances won’t appear and disappear weekly. Maybe right now, but not in a few weeks or months from now. The dust just needs to settle.
Every service with open protocols that isn’t centralized does the same and nobody has a problem with it, be it bulletin boards, IRC server or mail. You have multiple instances and can’t use a service when your instance is down. Thats why we are using the bigger ones and don’t run mailservers on our own. It is important that we could though.
We might disagree but I feel this is more a problem of getting used to it. In the end, we all want a decentralized solution, don’t we? Having multiple instances is just a part of the fediverse, that’s a pro not a con in my book.
