To be honest, I believe you are a little overreacting and misjudging the situation. I'd wager that the tenants that have CommSites enabled are in the single digit percentage. Microsofts communication was pretty clear: Rollout to first release begins by the end of Q2, which they did. With thousands of tenants, there are of course multiple deployment phases, which are splitted into the different release channels chosen by the tenant administrators, and then further splitted by Microsoft into different release rings.
If you want guaranteed release dates and full functionality you have to switch to the General Release channel. Otherwise you will be affected by a phased release approach that is out of your control.
I don't know about yours, but my tenant is set to "first release full tenant", which means we don't have it enabled either. As do all the other FULL FR tenants, and of course GA tenants.
There's currently a 1 week delay for the next FR ring, so in my opinion > no big deal, even though I'm in the same boat as you, want this desperately :)
