> MCU-class footprint (fits in 16 MB RAM)

That is absolutely not an MCU class footprint. Anything with an "M" when talking about memory isn't really an MCU. For evidence I cite the ST page on all their micros: https://www.st.com/en/microcontrollers-microprocessors/stm32...

Only the very very high performance ones are >1MB of RAM.

You don't necessarily need on-package RAM for this. I'm not sure I'd build a project around this, but 16MiB of RAM would hardly be BOM killer.

Actually it is. If you want to build a cheap sensor or actuator, than any additional component is getting expansive. Remember it is not only the external component, it is also the PCB space, is the production, and the testing after production. This adds up all to the costs.

When you use a µC to make it cheap, then you don't want to use additional components.
