I don't see why that's wrong, there were plenty of things that
discover their hostname by doing a reverse look-up of their IP.  And
he demonstrated several releases that worked exactly that way.

What are these plenty of things?  This is the first that I know of.
And the question still remains.  Is the OS looking up the hostname
at runtime or was it always the installer setting it at install time?

He listed several, and even showed a demo.

I listed one Apache, and I seem to recall Jabber and Dovecot did the
same thing (they don't ask your OS what it's host and domain name are,
it checks via DNS lookups).

That's a horrible idea!  And it would fail most of the time.
