I don’t see why this a problem. Both C and Rust give you 8 bit and 16 bit types to work with. It’s true that you may sometimes need assembly to eke out the last drops of performance on such small chips, but equally sometimes you don’t and C/C++/Rust are excellent tools for the job.

A 32-bit add will get turned into 1 8-bit add and 3 8-bit add-with-carry instructions. You won't even notice, unless to your point, you see a performance issue or start running out of code space.
