32 bit microcontrollers are well-supported, and often cheaper, more power efficient and with more features than old 8-bit uCs.

That is true but there are literally millions of AVR based Arduinos out in the world and I can confirm that they are totally usable with Rust.

Maybe, but 8bit MCUs are simple, efficient, have a huge community & resources, and more importantly exist in convenient DIP & SOIC form factors.
