A combination of high demand + strong incentive to keep access at a strictly controlled low level = this. I made it all the way to the green square at the bottom, following a long path along the left-hand edge. The process is a mind-boggling Rude Goldberg Machine governed by arcane and seemingly arbitrary rules riddled with exceptions. Having an excellent lawyer is both helpful (obviously) and depressing (in that it reveals just how many hidden controls are embedded within). The worst part is the long wait time when you have absolutely no say in the outcome, basically at the mercy of a remote faceless bureaucracy that can decide your fate and enforce it.
