You mean OEM as in “Boeing”? I thought you were referring to the runaway stab procedure, which is published and was discussed in the post-Lion Air AD. If you mean that there was no reference to the problems of manual trimming from a large out of trim state, then yes, that has not been in the 737 manuals for a very long time, and it ought to be restored. That being said the ET crew could have avoided the large out of trim state through the use of the pilot’s yoke trim switch. It was working, but it was not used effectively. If you wish to see what effective use looks like, look at the first Lion Air flight and the first seven minutes of the second Lion Air accident flight before the Captain transferred aircraft control to the First Officer.
That is not a transcript, it is a carefully crafted summary at best that leaves out a lot of details. Even so
At 05:40:35, the First-Officer called out “stab trim cut-out” two times. Captain agreed and FirstOfficer confirmed stab trim cut-out.
Does not at all sound like someone shouting fire and taking panicked random action.
Also note that the 'lion air emergency AD" casually mentions the possible problems with air loads in a note section and does not at all stress using pilot trim switches, which would be equally catastrophic if a 'stuck relay' trim run-away was happening...
