I'm getting the impression you haven't worked on that many bikes. Have you ever even installed a FD, yourself?
I get the impression you don't spend any time on this board. I have been the service manager at several high end shops going back to 1990 and have posted a ton of innovative solutions to a range of mechanical, hydraulic and electronic problems that people have requested here. There are maybe 4 or 5 people on this forum that are as knowledgeable and skilled as I am.
It is simply impossible to correctly mount and adjust several of the recent Shimano road derailleurs without the directions. Same to an extent with SRAM Yaw derailleurs. But even older derailleurs, like the first gen 105, have alignment procedures that you won't guess correctly.
