Just a few thoughts:

- you’d only be giving away your IP if you’re already giving it to relays (I.e. not behind a vpn)

- some clients will alert you if a profile appears with the same nickname and a different NIP-5, or one that does not validate (Nostur does this)

- the real value added by NIP-5 is a human readable way to find someone’s profile. It definitely should’ve never been called verification.
