They don't need to care about Nostr anymore than they cared about http to use LNURL, as long as it just works. Bolt12 simply doesn't work, only a few privacy larps really cared, and they were completely wrong about blinded paths. It was always just astroturf by Spiral and minor implementations jealous of LND's market share. The separation of concerns is key, not having to trust a nostr relay because of the encryption/signing already provides an instant transport network with the same accessibility of LNURL. Nostr is also bi-directional, it's not just noffers, but ndebits and nmanage for offers. Offers themselves provide flexible arbitrary data payloads for product details. (t-shirt sizes, sku's, zap receipts etc)

Why? Let LN handle the LN stuff, nostr can do the nostr stuff. LN wallets are perfectly capable of paying a BOLT 12 offer using the built-in onion messages, and they can figure out reliability if there’s ever an issue with it. Don’t try to rebuild what LN already has.
