@dahukanna Yeah, it's really a myth 'that you can move easily'. I've done it once and I'm not anxious to ever do it again.
As I understand it, it's not technically hard to improve it (e.g. also move your posts), it's a concern for abuse, which is frustrating. I've seen this movie too many times in my career: technologist's hard coding horrifically restrictive "correct behavior" when it should be so much more humane to keep the code simple and use a social norm to check for the potential harm.

Yeah, the tools & skills are generally not available.
It leaves ability to self manage any “migration” (it’s not a move) in hands of those who are technically able.
Using an analogy: when I literally move house-
1. If renting, have contractual conditions for ending. If owner, sell the house.
2. Usually have some notice & time to make the move, with my “stuff”.
3. Have services like change of address, to inform family, friends, service providers contact details that I’m moving.
