I really feel glad for you not suffering any of the remaining bugs of Android7, so you can totally concentrate on receiving security updates. Good for you. 
Considering the headline I think the shutdown bug turned out to be a show-stopper for new customers also in consideration of the total state of the FP2 which won’t get any better over time. Fixing this bug should have maximum priority over everything else.
To me it’s like one having to exit the (new) car through the trunk because all door locks are dysfunctional (by software control), but having the brakes in a perfect condition.
Or for the work-around - having to blow the horn for tree seconds to get the door locks responsive for opening from the inside. 
I think no one would buy such a car if only having the promise one of the next updates will fix it.
And how about the shutdown bug? Any news and progress on this to share for us? The community is still in a waiting position.
