Like most history, things get simplified and written from the perspective of the victorious over time. If Intel wasn't a vast corporation today we would be reading about some other late-60's LSI project as the genesis of the modern era, I'm sure.
These are not general purpose CPUs as far as I can detect, they were never sold individually for other applications.
Such dedicated devices were exactly what made the 4004 so special, it was used for calculators but could also be used in other ways because it was a true general purpose CPU.
