This would seem to have the same effect as waiting until after spec 
freeze to start using runways for focusing on reviews of 
implementations. And (MHO) I'm not sure we need help in reviewing more 
specs. While it's true that not a lot of people review specs, we do 
still also repeatedly approve more specs than we can complete in a 
cycle, every cycle.

I'd rather keep things simpler and not add spec reviews into the mix at 
this time.

Maybe a good compromise would be to start runways now and move spec 
freeze out to r-2 (Jun 7). That way we have less pressure on spec review 
earlier on, more time to review the current queue of approved 
implementations via runways, and a chance to approve more specs along 
the way if we find we're flushing the queue down enough.

What does everyone think about that?

Yes, this. The goal IMHO is to make an improvement over what we usually 
do, which is having our review efforts scattered across various approved 
implementations. If we could focus a bit and increase the chances that 
we're reviewing the same things at the same time, I think we might have 
a better completion percentage on approved blueprints in the cycle.
