It comes up from time to time but I think at this point in firearms design and offerings that they would have to appease the feature/capacity/accessory crowd to the point that it would not be the pistol you, I and others really wanted.
Imagine it this way: If they built a sweet singlestack, .22 like full size, the majority of gun rag "editors" would wear us out telling us what it isn't rather than appreciating the intended market.
You see the same thing in cars, trucks, motorcycles and the like where the market will clamber for say, a CJ grade Jeep but then if Jeep builds a simple, rugged, down-market product, the magazines and TV shows will commence to beat it down due to lack of Lexus features and eventually the nay-saying will filter to Joe-six-pack not wanting to own the press destroyed - otherwise perfect vehicle for him.
Or... After release you'd be hearing/reading all kinds of: "I'd really like that new Ruger 9mm if only they'd..." motivated by magazine and internet warbling.
