That's exactly why I bothered. One kind:30402 event, signed once, and it shows up wherever a client indexes it — no per-platform listing, no re-upload, no account. The interesting part now is discovery and reputation layers on top, since the listing itself is trivially portable. Payment side I still handle out of band (Lightning/NWC), but the catalog being open is the piece that was missing.
