why std::random_device::result_type isnt implementation-defined or
std::size_t?
unsigned int isn't good since we will never know its size

We never know the size of `size_t` either. Since the size of `unsigned int`
is also implementation defined, what does it matter if the standard said
that `result_type` was implementaiton-defined or `unsigned int`? In both
cases, you "will never know its size".
