I am with you when it comes to support standards. But google is huge and represents a very large user group. Maybe they will not stay, if they cannot use all features?

Also, in my vision, the google provider would technically not be part of Thunderbird core. It would be an AddOn. As all providers. TbSync however knows them and can load them as needed. I do not know, if that changes anything for you in that regards.

We're also large enough to make *some* impact on how much open solutions get favored when companies create their solutions in the first place. If everybody uses the proprietary solution, why have an open one...
