>> But PIC came from it's original use, as a Peripheral Interface Controller. Thinking back to 1977. I don't think that programmable microcontrollers were aimed at "peripheral" control (a "peripheral" was something to attached to a computer, not something that WAS a computer.) So I'm inclined to believe the GI data sheet that says "programmable" instead of "peripheral."
