> I can't imagine someone using an RP2040 in a real product

Why not? It's a great chip, even if it has some limitations. I use it in several of my pro audio products (a midi controller, a Eurorack module, and a series of guitar pedals). they are absolutely perfect as utility chips, the USB stack is good, the USB bootloader makes it incredibly easy for customers to update the firmware without me having to write a custom bootloader.

I've shipped at least a thousand "real" products with an RP2040 in them.

Given the way the RP2040 is set up, I cannot conceive of a proper secure boot chain for it. So, for basically everything I work on professionally, it's a non-starter. I think the key in your use case is that "hackability" is a feature, not a potentially life-threatening risk.
