Lightning is just one donation option anyways. I'd like to see the Funding Tag expanded so it can be more than just one link. I remember nostr:npub1yvgrrzf4dnmu30qfhw95x87ruu0g2kpv3a64h8hpvqsre8qeuspsgd6pv9 mentioning make it similar to linktree so when you click it you get a list of donation sources.
