Serious question, no offense or provocation intended: With this stuff being baked into Hubzilla and, apparently, also design-wise into Bluesky / AT, can anyone out here involved with the #ActivityPub specification process outline why nomadic / easily portable identity isn't built-in here by design? Looking at the (to-be-expected) dynamics of instances going up and down, blocking each other or moving to newer, different pieces of software, this seems an absolutely obvious requirement, so I wonder why this has been left out of the standard / spec?
