Airlines see it too, and all have made a variety of systemic adaptions in training and line ops in recent years. 121 as a whole and most individual airlines have a large enough data set (which they actually collect and analyze routinely) to spot trends and react.

Most 91/135 operators are too small to benefit much from a data-driven approach at the level of individual operators... the three near-misses that occurred prior to the smoking hole happened at other operators so the accident operator had little visibility other than waiting for the NTSB. IIRC alphabet groups like NBAA do share some data, but maybe the FAA does need to weigh in... the system has changed and it's not reverting to how it used to be for many years, so it's reasonable that some adjustment needs to happen.
