My point is that if you increase the likelihood of an event (trim runaway) you are also increasing the likelihood that your last line of defence (pilots) may get it wrong, especially if you don't reinforce specific training. MCAS increased the risk of a catastrophic trim runaway and where was the training? The statistics, if ever divulged, will be interesting.
A quick search of the ASRS database returns three reports of runaway trim on 737's. The search engine is a bit fiddly, so there may be more in there. Also, ASRS would only have a report if it was voluntarily submitted by the aircrew. I believe the FAA maintains a more comprehensive database, but I have not seen any reporting from them.
