I meant something more specific -- are any implementations (practically, browsers) keen to expose a UX that allows you to type an arbitrary hostname into it and wind up resolving DNS through that host, and can explain their reasons for doing so with a hostname rather than a URL (which again is how search engines are configured currently)?

We generally don't discuss UX in the IETF, but it seems like if we're going to have a UX-driven argument determining the protocol, we should at least have someone who's interested in following that path and can explain why this so important. Otherwise it feels too much like engineers who have no business making UX decisions taking a punt.

And that still doesn't address the mismatch with the intended use of .well-known.
