I do get those climbs somewhat confused. Waverly Wafer is the 5.9 bolted flake, correct?
I remember it to be a super fun, straight forward but strenuous 5.9. The flake is clearly somewhat delicate and its easy to see how a fall on gear in the flake would be unsafe and may even destroy the flake. Strict purists may rue such bolt placements, but I thought in that case they were reasonable.
Perhaps another apt comparison is Perry's Layback on the Grand Wall. Obviously not delicate or lacking good gear, but you'd need about 6 #5's to protect it. hard to say from an ethical point of view, but I sure had fun climbing it.
