You cannot remove the fact that this procedure was once published, that is an established fact. Removal of it from recent manuals cannot change the reality that is already proven. History tells us there never was anything seen wrong with the trim system or it's procedures in the 60 years before this - suddenly finding something there now is far too close to 20/20 far-too-clever hindsight.
Having dealt with a scenario like this in certification (different industry, still safety related), it's a perfectly reasonable point. A lawyer and a paranoid engineer going through the manuals may have suggested deletion. The fact that it had been published doesn't matter, their point would be "we can't recommend this as a procedure any more"
At the end of the day we don't know why it was removed so it's speculation on both sides.
