I think you are far overestimating 1970 electronics :-)  The week
based scheme was a compromise forced by number of bits available
and how much electronics could be dedicated to the task of receiving
the signals.  For a long time the almanac was something you had to
manually enter into the receive (which is probably why almanacs are
still published by the GPS control segment people).

Never attribute to malice what can adequately be explained by incompetence.
