That will make the price of the Nikkor 58mm f1.4 seem even more... odd?

 

My understanding is that the 58mm f1.4 deals with correcting coma and apparently it is an expensive thing to do.

 

Of course, you will also note that it's a 58mm lens and not 50mm. Nikon didn't add an extra 8mm just for the hell of it. They already have more 50mm varieties than I have fingers.
