If other organizations are anything like us, the issue is not in adding
the values to DNS, it's in working out what the correct values are.
My preliminary investigation suggests that while we may be able to add
"issue" records for specific foo.mozilla.org domains (e.g.
addons.mozilla.org), and an "issuewild" record for mozilla.org itself,
it will be very hard to have an "issue" record for mozilla.org because
we have subdomains which are managed by third parties (e.g. for our
mailshot infrastructure), and they could change their SSL provider at
any time without informing us.
