Nope. The extra sensor was part of an options package. When ti should have been standard and required for obvious reasons. And that is just the tip of iceberg on the stupidity Boeing design on that aircraft. I believe that one of the design flaws still exists. The “STAB” switch does not have a position to cancel all computer control and still have Electric control from the yoke.
You sound like you know more about it than I do, so I will bow to your superior knowledge on the matter.
And yes, it is stupid to cut off electronic control from manual adjustment of the trim.
