Change Minecraft's Microsoft account

A lot of parent buy their kids the game on their account, but later it becomes annoying to relay on their account and passwords. I suggest to make it possible to transfer the minecraft account to a different Microsoft account. In order to protect the account maybe make it so the Microsoft accounts have to be in a family together plus it will take 30 days for it to transfer. Even though you can just buy another account all of the progress in servers and realm would be gone and so will the capes from events which aren't possible to get anymore.
