As someone that changes the ride 9 frequently I feel picked on!
IMO with the Hi/Lo style flip-chip it's all about giving you that last little bit of adjustability to get the bike closest to max comfort/performance for you as individual, they aren't designed to be flipped every other ride.
With the ride-9, there's enough adjustability that depending on where I'm riding and how I plan to ride, I can set it up to suit the conditions. This normally means one of 3 settings (super slack, slack but with higher BB clearance to avoid some Youies rocks, 'trail riding' mode). Along with being able to lengthen the chainstays it really does change how the bike rides
Spceialized (I think) did something similar where one of their bikes came with adjustable headset cups (and something else) that let you quickly change head angle etc depending on where/how you are riding.
It can be gimmicky, but it also does potentially allow you to own a single bike, probably around 140mm, and run it as both as a ' big' bike and something that's fun on the more mellow trails
