Bzzt. Wrong.

As you said, this is all hypothetical. Just as Julian said:
``hypothetical bit stream''.

How did you get ``frame'' involved?

You're mixing high-level, and low-level implementation.

Once you have that bit stream ready and built, as outlined
above by me, _THEN_ you pass it to the upper layers
which will take care of sending and reordering, and what not.

AND IF an implementation can ``see'' that it can optimize
things just because their bit/byte order is such an such,
then so be it, BUT the explanation should be formal enough
and NOT refer to any particular implementation.
