Seems right! I think some of the biggest opportunities are improvements to technology that anticipate and correct for downstream failure. To some extent sophisticated manufacturers already do this—eg constant airflow fans installed in restrictive duct systems tend to fail prematurely. Many of Mitsubishi’s air handlers now limit external static pressure to .8 inches of water column, I suspect in response to these high failure rates.
