That's cool, and I like the design since it already establishes a way to express different payment methods apart from "native" ones like NIP-57 and NIP-60. However, there's definitely a privacy flaw for some wallets that shouldn't use static addresses, such as on-chain addresses, where reuse is not recommended.
I'm drafting something for markets and merchant payment preferences. We're using NIP-78 as a way to track xpub index. Also, for markets, we're writing a spec where we use a 'payment_preference' tag in the kind 0 event for the merchant to determine how they want to be paid for their services/products. The value of payment preferences can be lightning, cashu, or manual as an interactive/server-assisted method which is not Nostr-native
