Are you saying, when this technology comes available, all I have to do to set up a lightning wallet is copy and paste my nsec and add @ npub.cash in the zap field of my nostr profile?

That would be like, one step away from making it so all I have to do is click a button to set up zaps.

And wouldn't that also be like, one step away from letting me have my zaps automatically converted to on-chain bitcoin at a designated withdrawal address, whenever the balance reaches certain amounts and transaction fees are within certain limits?

And wouldn't that be like one step from using BIP-352 "silent payments" to avoid address reuse from entering a single withdrawal address? 

And wouldn't that be like one step from replacing the one-button activation feature with... letting me just enter my withdrawal address as the only step in my setup process, with reasonable presets in place for on-chain conversions and stuff like that?

And wouldn't that configuration result in me being able to trust npub.cash zap addresses as a safe way to send money?

IN OTHER WORDS:

Are you guys... let me count... 5 steps away from making me adopt lightning to zap your users?
