Sorry, Whisper35, I didn't see your post until now.
I wondered about the same thing. The short answer seems to be "no". It's easy to grab bushings from an unused implement and put them on - sort of like moving drilled pins from one to another. It's convenient to have them on each implement ready-to-go though.
At this early stage, I'm not wild about the iMatch. I also wasn't wild about the Pat's Quick Hitch I bought for my old JD755. In both cases, the problems might be just new-gear stiffness and my lack of experience, so... ask me in a year. For now, it isn't saving me any time but it definitely is saving me some physical grunt-work manhandling implements into position. Many of my implements are older and may not be iMatch-compatible, so I still have to see whether that is a big deal.
So far, the top'n'tilt seems to save my bacon when I use the iMatch. Without it, nothing lines up quite right and I imagine I'd be back to wrestling implements around, half-an-inch at a time. My implements sit on gravel or on blocks on gravel, not on a level concrete floor, so no doubt that is part of the problem.
There's definitely a learning-curve and coordination issues in play and (he adds sheepishly) I'm no longer young so maybe those are the main issues.
