Comment 6 for bug 636918

In few months all owners, drivers, bug supervisors, and security contacts will be granted access to project bugs regardless of subscription. That means subscriptions will only provide communication to users in project roles. We want to switch to subscription because it will provide levels of communication--the current approach is an unregulated torrent. I see two courses of action:

We announce we are dropping the automatic mailing to owners, the user can subscribe if he chooses
or we subscribe the owners, then make the announcement, where upon the user removes or changes the subscription.
