I have run fully self custodial lightning before with a node at home, my own domain for lightning address, etc. Let me put it this way, I risk lose FAR fewer sats in custody on a custodial wallet than you risk in fees and channel open/closures. Experimenting with self-custody lightning is absolutely recommended. But you will lose a lot of sats and you will cause other users to lose a lot of sats by recommending they use ZeusPay for receiving zaps on nostr.
