In my case I migrated the account, played it once to check the migration was successful, and then a few months later my account randomly doesn't own Minecraft anymore.
I opened several tickets and the only response I got was "saar we're sorry saar but this is up to the microsofts, no you cannot contact the microsofts saar".
So they just straight up stole my fucking game for no discernible reason and I have no discernible course of action. Cool!
