For example I would selfhost Mastodon with me@fedi.com but then decide to change the server software to GoToSocial but keep the same me@fedi.com. Would everyone who was following me@fedi.com keep me in their follower list or would whole fediverse crash?
quokka.au changed from Lemmy to PieFed and it was ok once the remote servers refreshed their public key caches, about a day.
Mastodon to GTS could turn out different but yeah.
Very interesting.
Didn’t think such a “dirty” method of moving from Lemmy to Piefed would work
