This shouldn't be a problem if the service id (onion address) remains
the same across IP address changes. If the HS is stable then, as far as
I understand this system, it should maintain its name.

Right, which is why I'm not sure a centralized naming system will work
in this environment. 1) The user loses the self-authentication of the
service (whether or not they understood they had it in the first place).
2) It's not possible to guarantee a name maps to the same hidden service
over long periods (see 1.) and if trust in placed in the name then this
is important. If I visit https://google.com I expect not to be MITMd
and I expect to receive a reply from Google Inc's webserver.
