Able to allow guest access for special teams (o365 groups) only, not all
Same concept already in for SharePoint Online sites, disable guest access on tenant level and set for special single sites only "allow external sharing", must be possible also for teams (o365 groups), in same way, current situation at the moment a show stopper for us, current domain handling not a solution

To add to this, the real requirement of guest access for a Teams Admin to allow guest users to be invited to only SPECIFIC teams. Right now it seems that it is an all or nothing thing. You either can allow guest users to be invited to ANY TEAM or NO TEAM. There are certain Teams that we use that we want to ensure that guest users don't get access to without having to rely on the Team owner to just not invite a guest user.
