1) To quote myself: "I'm not saying email self hosting should not be done, I just say a bit of planning should be done". I self host my email. I just meant it is not "just rent a VPS and slap some docker containers on it"

2) I never said receiving email is a SPoF

3) Please explain in detail what do I do in order to keep receiving emails using "me@johndoe.com" after johndoe.com gets undelegated. I do not know of a way and would very much like to know. If there is no way.. It is a SPoF.
