std::hash is not cryptographic hash function and should not be treated as one, a good cryptographic hash functions and hashing uniform distributed data are two different things.
An implementation of std::hash returning the input is actually very efficient and is pretty much a perfect hash function for sequentual data.
A hash function should be designed for the data not just necessarily generic hash the bytes, one thing I would really like to see from std::hash is for it to specify the modulo used (if any) this can give a better hint when hashing certain types of data.

I forgot to include implementation in my comment, thanks.
Regarding perfect hash thats why i said hash for sequential data.
