On pages like
https://phabricator.wikimedia.org/settings/user/Jidanni/page/emailpreferences/?
there are like 100 email prefernces.

Alas one much change each one at a time.

Please add "change all to" and the have the three choices.
[ ]Change all to ignore
[ ]Change all to notify
[ ]Change all to email.

As far as versions are concerned, I am not a admin there. I don't know it.
