The short answer is because long long and long are different types.
Changing the underlying type for uint64_t and friends would break
user's code as the underlying type changes.
And it isn't portable, which would make code written for FreeBSD much
less portable. The only portable way is to use the PRI* macros. We
can paper over this fact, kinda, in FreeBSD. So long as we never have
an architecture where long long isn't 128 bits.
In short, this is a really bad idea.
