I don't think this is walled-garden behaviour. No one's stopping you from just using the same user info for every server you join, with no consequences to doing so. You don't need an email and data doesn't sync anyways, so there is no need.
But you will have to do the hassle of making another account on each server

The last update to this github issue was over 3 weeks ago. Also why should anyone care when they already said its technically possible but up to the servers to share their login database?
