I think I get it.

Personally, I like the idea.

And something that comes to mind, Mastodon, Lemmy and PieFed all have methods of account migration. Perhaps such Bytescape tool could integrate to those too?

And further on that, apparently Piefed doesn't import info that it doesn't federate with, e.g. Kbin.Social since iirc it can't be reached (correct me if I'm wrong pls). Also maybe that happens with Mastodon and Lemmy but haven't checked. But if I'm right on that, it would also apply to active but defederated instances. So maybe such potential integration could be used to preserve information that would otherwise be lost as it's not imported?
