If the SP1000 was a "step backward" technologically from the Spotmatic-F has no bearing on which was the final model designed.
Pentax wisely saw an opportunity to sell a popularly-priced model using tried-and-true technology,
one that many customers were accustomed to and preferred, utilizing an existing stock of parts and existing tooling.
Obviously Pentax sold many SP1000's, and the experience was clearly a model for the even more successful K1000.

It was a helluva gimmick. It worked!
Seriously, "marketing gimmick" may have been the wrong phrase. I didn't mean it to be a perjorative. Its just that the SP500/1000 were introduced AFTER the SPII and SPF, both of which had builtin hotshoes. The SPF had open-aperture metering. Stop-down metering was one of the knocks that fans of other brands always levelled at Pentax. Their answer was the ES, ES-II and SPF. That the SP500/1000 sold as well as they did, puts the lie to that complaint. Heck, I still do stop-down metering on my K10D, when I use the Super-Takumar 50/1.4. The SP500/1000 were slightly modified original Spotmatics, hardly new cameras.
But, I do suspect that the idea for the SP500/1000 came from the marketing department, not engineering.
They did serve their purpose well, which was to provide a lower cost, entry level camera. I'm sure that the devlopement costs for the SP500/1000 were minimal. It was mostly a matter of deciding what to leave off of the camera. But, they were perfectly good cameras. After all, they were really just Spotmatics, which is one of the all-time great cameras, IMHO.
And, 100,000 cameras for Pentax during that period wasn't all that many. Remember, during the Spotmatic era, Pentax outsold Nikon and Canon, combined, at least in number of cameras sold.
I've seen some claims that the Auto 110, which was only in production for about three years, sold more than two million cameras. And I don't think you could consider it a real success, since it was cancelled without a replacement (I'm including the Auto 110 Super in those numbers).
Given that the K1000 was really just an updated Spotmatic (as I said before, nothing wrong with that), the Spotmatic and its progeny had a pretty good run. The Spotmatic was first shown in 1960; first sold in 1964 and didn't go out of production until 1997, when the last K1000 was made.
