Why was "unsigned integer" not considered as a native data type in Fortran

>From what I understand from the simulation expert's posts, he was able
to generate Pseudo-Random numbers very efficiently with C, using
unsigned integers.

I can see that the unsigned integer type could be quite useful and
would the experts please explain why it couldn't be introduced as a
native data type in Fortran ?

Also,

If we are using N bits to represent integers,

The set of integers from -2**(N/2) to 2**(N/2) - 1 can be obtained by
translating the set of unsigned integers from 0 to 2**N - 1 by the
constant -2**(N/2).

Can this fact be used to efficiently define unsigned integers as a
derived data type ?
