The concepts that are in the library were added because there is a specific
use case for them in the library. We didn't add concepts speculatively
because they might be useful, or just because there's a type trait. So
there's no arithmetic concept because there was no use for it.

You can define this yourself, or you can just use is_arithmetic_v in
constraints.

Yeah it would be zero WG21 work and little SG work I guess..

That's unlikely.
