My recollection is that traditionally the first host name is
considered the canonical one.  'man 5 hosts' backs me up on this :)

I don't recall seeing 'localhost.localdomain' back in the day -- but I
know *I* didn't put it there.  If Fedora does it then that is standard
enough for me; we're talking about thousands or millions of hosts
here.

I don't have any other entry in /etc/hosts.  My machine has no fixed
address and is not in a domain.  This, I believe, is extremely common
among laptop users.

Perhaps if only "localhost" and "localhost.localdomain" are found,
Emacs could fall back to gethostname(2) or uname(2).  With glibc the
latter appears to try to return the domain name as well.
