If you want to simplify, why do you care if you make AMEX mad? It’s a commercial relationship, not a contact signed in blood for your soul.
If you’re not really interested in getting any more AMEX cards or bonuses, why would AMEX care if you end up back on your BCP and still paying that $95 annual fee!? Worst case is you get pop ups for a long time… but if you don’t want the other cards, why does it matter?
