Not important. It just seems like as something that's effectively a byte
it could be nice to have a `Copy` type for it.
Not sure why it would really be a hassle, given that it is its own type
and the internal representation shouldn't matter to the rest of the
code.
But no, it's not important, and can be changed later anyway.

Right. I don't think it makes sense this way, mostly because the
constants aren't `pub` anyway, so if at some point one would need access
to them, the crate would need a bump to add the `pub` *anyway*, so it
could then be turned back into a const. (And for crate-internal access
it's also just a tiny commit before using it...)
