If you suggested to treat bitset as an array of bits, then it would have
to be an array of 1 and 0 - a thing that hardly could be useful.

Unfortunately, your suggestion would make traditional arrays and bitsets
look undistinguishable in strace output.  Could you think of a change
that wouldn't introduce that kind of regressions?
