I am not a BTCPay customer today, and I anticipate a feature request that may benefit BTCPay customers by reducing the custodial risk @ROCKSTAR :

If custodial account reaches (a user set, non trivial amount of) X sats, automagically transfer from my custodial to my non-custodial wallet. 

 Already possible with Prism plugin I believe 😉

It's the flow they used at Baltic Honeybadger last year

 🔥 BTCPay is already in the future. 

One further product learning from Damus for yalls consideration:  if something is hidden deep in settings, many people will never find it.
