Poison pilling skills is a thing, though finding evidence for it is difficult given the crux is an absence of information. The baseline instruction and training is given to the model by the expert, but edge cases are willfully neglected. The degree of neglect generally determines how detectable it is, but if all the SMEs are in on it a lot of them will probably persist. Effectiveness and impact are obviously relative to the system and the edge case. Not particularly different from the fallout previously seen during the offshoring era.
