Since time began (Fedora 7), all fedora bugs in bugzilla have had their
"QA Contact" field set to: extras-qa@fedoraproject.org.

Bugzilla describes "QA Contact" as:

"The person responsible for confirming this bug if it is unconfirmed,
and for verifying the fix once the bug has been resolved."

However, also since at least 2007-04-20 emails to that address go to
/dev/null. (Before that they went to a linux.duke.edu address, so I am
not sure where they went).

I'd like to propose dropping this from all Fedora bugs.

It's a useless extra email that bugzilla has to generate, network has to
send and deliver and we have to drop in the bitbucket.
