This sounds to me like a good path forward, to mitigate the review 
bottleneck (and scarily low bus factor) without significantly lowering the 
level of quality required.

I'll be adding some of these new approvers on patches of mine where there 
already is one approval from someone (I guess all patches with the libc++ 
group reviewer set will show up in their review queues now too?) to try it 
out.
