That's such a strange piece of UX. As a typical user, who on average consumes content rather than produces it, what I care about is that my list of followed accounts migrates with me so that my feed stays relatively consistent. As a content producer I would also care about my past posts migrating with me, which they don't. Having followers continue to follow me after migration is only the primary concern for the "influencer". I get that "my friends can still find me" is an important feature but who thought it was ok to skip the other two?

Followed accounts are easier to do manually; there's a simple export / import interface that existed before the account move feature.

I will note that for you "as a content producer" the uniformly reverse chronological presentation on Mastodon highly penalizes older posts (even a day old!) to an extent that is pretty rough to get used to, and that makes those older posts pretty irrelevant to move over. This is much like Twitter before its engagement-maximization algorithm days, though.
