Now that we have ImportC, maybe he he can be convinced to

The arguments from that section are:
- 32-bit integer operations are often faster than smaller
integer types for single variables on modern architectures.
I'm not an expert in modern CPU architecture, but I'm extremely
skeptical of this claim. I doubt the difference is even
noticeable with modern compiler optimization techniques.
That was the argument Walter made in 2022 'this has carried over
into modern CPUs':

I don't know enough to comment on that.
- Promotion helps avoid accidental overflow which is more
common with small integer types.
I got 3 words for you: Value Range Propagation. We pay for it,
so we should use it wherever possible.
How would that fix the problem? And ideally in a way that doesn't
break existing working code.
