I'm sure you did consider those libraries. However, they specify bitwise operations on integers of somewhat uncertain range, which opens a can of worms. Operations on bytes (exact integers in the range 0 to 255) are much easier to specify and are all you need for many useful operations on byte vectors.

That is my specific question: did you consider including bitwise operation on bytes only?
