Reverts #22328

alternative to nim-lang/checksums#6

Is this really necessary? What's the problem with nim-lang/checksums#6?

This "feature" was introduced without any RFC, documentation, changelog entry, tests or review. I still think it's a bad idea to allow adding any two Ordinals. Wouldn't it be enough to add an overload for uint64 specifically (or SomeInteger)? Then at least we wouldn't be able to add *arbitrary Ordinals. It also breaks the JS backend, which currently relies on the second argument always being an int.

Perhaps, I will test that.

Doesn't += also support some integers as increments? Is that proc broken for JS as well?

No, += only accepts arguments with the same type.
