My biggest problem with it is forgetting which system I booted into when I use the same desktop environments :P and yeah configs can get out of date and inconsistent but I usually just blow them away since I'm not into customizing my desktop much
? But when interacting with local content your name ha sno server associated with it, so the server info is only present for federated content.
Bringing the old server back up configured with a new name could... Maybe send out duplicate content with the new name? Idk enough about activitypub yet.
I added 3 tbs lead but it tastes kinda funny
