Yes, but most of that is true only in the most direct sense. The bypass may be necessary - the overcrowding is a disaster waiting to happen, and causes much aggression and stress. But that is all caused by WDW's own development of the property. A second MK, or fully developed other parks would have prevented the current overhaul of the MK.
The MK is meant to be awe-inspiring, fully themed down to every inch. You can have stuff everywhere for people to gawk and fawn over - just look at the MK 1.0, or DLP specifically for arcades.
Every intervention in recent years may have been 'necessary' from an operational point of view, but that is a necessity that is either the product of failures in the development of the property as a whole, or of unwillingness to go for the big, bold other solution, or even a simply deceptive necessity. For example, with two nighttime parades, fireworks, and a 1:00 AM closing time the exit stampede would be mostly solved. If that sounds excessive, that is exactly what WDW did during its heyday. And the MK had fifty percent less visitors too. If they now add some basic themeing to some shrubs while herding the masses out through backstage, that may an improvement in a strict sense, but it is of the kind of charging you $19.95 for ketchup on your fries instead of $19.99.
