Dunno, that doesnt make a lot of sense. Squarebody style was the same from 73-87 (with some carryover models as always) that's 14 years, then shitbox from 88-98 that's 10 years plus carryovers...
More likely just like anything, either they just didn't sell enough, mismanaged their company, product was crappy and they couldn't fix the problems, who knows.
I think you could probably make one easily enough - except for one part, the weatherstripping would be a beotch, trying to come up with something that you could form to the shape of the opening and also be rigid enough to serve as the window channel above the bottom line of the glass, in other words for the section that is in the actual window opening, running the glass frameless like a shitbox door window.
An older truck of mine had a C.R. Laurence power slider rear window, that worked OK, obviously not anything close to having a full roll-down rear window and after a few years it got kinda slow and crappy, had to help it close.
