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.

You can use wider types, maybe even floats I can't recall, they'll get lowered to the target architecture and the generated code will be in terms of narrower registers.

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.

AVR GCC totally lets you use floats, I'm not sure about Rust. It does as you'd expect result in a lot of code, but it seems correct.

It does, but they are unbearably slow.
