In my experience doing support, this is a give them an inch and they’ll ask for a mile situation. Power users are the worst when it comes to asking for more features or more settings. I had better luck with very limited settings and saying take it or leave it. Would just tell them straight up “What you want has a 0% chance of happening. Happy to refund your money.” Hardly anybody took me up on it and it greatly reduced ongoing support conversations that went nowhere.
