Haha, that could very well be the case. But I feel that's an unfair comparison. To me, that's similar to saying: Sure the Nissan GT-R is a very fast car, but the Nissan Altima is easier to park and easier to drive in typical everyday conditions. True, but that's not why the GT-R was made for. It serves a very special purpose, much like a f1.2 lenses.
I'm the type that feels if you have a f1.2 lens, you should only be using that aperture 90% of the time. It is a very specialize lens, and I can't knock on the built quality of the 85mm f1.2 though.
Maybe we'll be lucky and have a Pentax equivalent one day.
