I’d think my abbreviated version is; “NIP-05 enables your npub (complex identifier exclusive to you) to be replaced with a identifier that looks similar to an email address. Npubs are used in the background, NIP-05 is your easily shared identity.” I do like the preciseness of it being a third party that (usually) provides it but that could be off putting in the immediate first steps of an onboarding exp.

Probably not.
