Isn’t there some dynamic at play where STM will put one of these on a board, that board becomes a “standard” and then it’s cloned by other manufacturers, lowering cost? (legality aside)

i.e. it takes some time for new chips to hit cost targets, and most applications don’t need the latest chips?
I don’t know a lot about the market, though, and interested to learn more
Some chips that have come out in the past 3 years with Cortex A7:
Microchip SAMA7D65 and SAMA7G54. Allwinner V853 and T113-S3.
It's not like a massive stream of A7's. But even pretty big players don't really seem to have any competitive options to try. The A-35 has some adoption. There is an A34 and A32 that I don't see much of, don't know what they'd bring above the A7. All over a decade old now and barely seen.
To be fair, just this year ARM announced Cortex-A320 which I don't know much about, but might perhaps be a viable new low power chip.
