Ummm... has an enterprise PKI ever been included in Mozilla?

Also, who's to say that domain ownership/control and email account
ownership/control aren't authoritatively evidenced by internal systems
(technically, all someone external can do is verify that someone has
access to the the machine pointed to by the DNS, or can access the
email, both of which rely on the capability of the actual owner to
adequately secure their systems -- but if a policy is in place that
only employees are authorized to have 'control' access to systems or
email accounts within the domain then that business evidence is more
authoritative.

(In any case, enterprises that act as RAs are unlikely to be acting as
RAs for domain-validation, they're much more likely to be operating as
RAs for "entities authorized to operate on the enterprise's behalf".
Which is a perfectly legitimate thing for them to do, as long as the
bounds of trust are carefully defined and preserved through the client
user interfaces.  which they never are.)
