The doo dis-connect is a carryover from the XP chassis to get a rider forward trail-designed chassis to roll easier. Early attempt to fix an extremely rigid trail chassis before T-motion and flex edge (thinking about it, don't think the Rev had a quick dis option). There are pros and cons to eliminating borrowed spring rate (an anti-sway stabilizer bar), but as stated, if you want to do it "right", you need more individual spring rate (or air) after pulling the stab bar. Did it back in the Rev days, and while still abit of a compromise, unless you are hammering trails, you can find a good setup for your terrain and riding style. Without a spring rate change, you do get softer tip in, but it's much easier to bottom/break a front shock, and you do need to be more active on the chassis to comp for the loss in pitch control. Pretty sure it was the early M's that started coming without a stab bar and with floats from the factory, calibrated for the missing stab bar. Not a coincidence that was the primary platform for the early wrong-foot-forward technique (alla CB and BR).
