I don't know about this technical talk, but all I would love is to be able to use autofocus without having to go back in manually and move the focuser back out to the calculated spot - which is ALWAYS better than the final focus point that EKOS chooses. My whole routine has been to run autofocus, then manually move the focuser OUT about 800 points on the ZWO EAF (to prevent mirror tilt), and then back in to the previously calculated focus point. I image at 7,000 ft in central New Mexico, with humidity levels in the single digits. The difference between these two focus points is very noticeable and frustrating that EKOS aways chooses the worse point. At least it is consistent in that regard.
