From what I understand from reading PPrune forums, pulling the circuit breaker for trim irregularities is the de facto standard operating procedure on the 737, and has been for over a decade+.
Hopefully they find the CVR and that gives us more insight into what the crew was thinking. It is odd that the pilots struggled with trim controls for ~11 minutes and didn't think to disable it.
The media has focused on the new MCAS system on the 737-Max, but I think that is somewhat irrelevant, considering that the procedures for addressing trim irregularities non-Max models are the same: pull the trim circuit breaker.
