Given a private network and the need to monitor it in a private 
company[1], we generated a certificate like this for internal use signed 
by a company-internal trusted certificate authority.

Also, given the Subject Alternative Name extension, it is quite possible 
to generate a "godmode" certificate for gracefully redirecting proxied 
HTTPS requests to an "Access Denied" page or even 
nefarious-purpose-logging machine.
