I got almost all of my wishes granted with RP2350
> A USB DFU function embedded in boot ROM is flatly undesirable in an MCU with no memory protection.
Are you saying DFU is not useful without an MMU/MPU? Why would that be?

It's certainly useful, but having it embedded within the hardware with no way to properly secure it makes the RP2040 a non-starter for any product I've ever written firmware for.

Not the RP2040. That chip has no boot security from anyone with physical access to the QSPI or SWD pins.
