@rauschma Having said this, however, of course email addresses are also domain name system dependent. And if we had a system of user ids independent from server ids, then we would need some sort of registry which resolved a user id to the address of the place where that user's content could be found, which would be one of
1. Centralised; or
2. Hierarchical, like DNS; or
3. Easily manipulated by bad actors

Given that choice, tying user ids to server ids, especially given that we now have pretty good user migration tools, looks like a very reasonable choice.
