The pi-pico does have that cute PIO state machine though to baby sit GPIO and get single cycle granularity out of it.

Yep, I suspect that will be the path forward. Same high level strategy, but integrated into a single package. It will be interesting to see if the babysitters remain state machines or if they grow into tiny little microcontrollers.

Or tiny little FPGAs connected to the GPIO lines would be neat too.

Many automotive MCUs have complexe timer coprocessors integrated for hard real time I/O purpose. Examples are GTM, eTPU and N2HET that I know about. Does the PIO work in the same way?
