That is certainly one possibility. The other, of course, is that there was pressure on both flight crews and technicians to keep the metal moving. It was an unusual choice for the penultimate Lion Air 610 crew to continue the flight to destination with an active stick shaker and an inop stab trim system. Maybe they realized this at some point and did not wish to highlight themselves by writing all the details in the logbook. It would not be the first time such a thing has happened.
Similarly, it has been suggested elsewhere that the Lion Air maintenance staff was under pressure to minimize downtime on the fleet which may have contributed to a less than thorough diagnosis and repair. IIRC, there was a history of problems with this aircraft even before the penultimate flight. I imagine these possibilities will be looked at by the official accident team.
