This question comes to me because since we cannot hop through instances (AKA transfer from one instance to another your account) I’d like to create an account into another instance, for research purposes, but if this ‘feature’ comes in a near future I’d love to bring my main account to said instance, preferably with the same username and if I have it “mirrored” (same username) I think that’d make it impossible.
From my understanding it should be possible, I think that’s the case with many communities/sites, but I’m not sure here.
I hope I’m being clear.
While this is absolutely true, the more accurate analogy is with email.
Bob@gmail.com and Bob@yahoo.com can still communicate, send emails to eachother, etc. Even if it’s the same person operating the keyboard. Separate platforms, common protocol.
