I don't think there is a way of deducing endianness through templates since
templates deal with integer values and not their binary representation.
Through constexpr maybe?..
I can't speak for the committee, but my understanding is that C++ Standard
tries to avoid dealing with binary representation of data to not limit
implementations. Things started to change though with adding <cstdint>
types.
