The thing about f/stop printers is that I might imagine the bulk of those interested in that approach have probably also already invested in (rather expensive) timing units, and evolved their own workflows around those. My guess is that they may not want to give those up either.
Pretty much, same with how my 45MXT is setup too, but it's nice to see it taken seriously, maybe one day for us Beseler users...
