Well, Dryden is inaccurate in a lot of his comments. (I have no idea where he is getting the 10 inch pad width from, maybe he is confusing depth with width. Whatever.)
Let's get to some meaningful specifics:
Wrong. NHL Rule 11.2 states the following:
Let's consider Dryden's comment about the chesty:
Well, NHL Rule 11.3 finishes with the following:
Now, it may be that Vasy's chesty is legal in the crouch position, and then raises the shoulder cap protection when down in butterfly. If that is the case, then rule 11.3 could easily be amended to include the wording "or in the normal butterfly positon". We've been through this with Garth Snow, this is not a good argument for compromising goalie safety when a simple rule enforcement or rule amendment will do. And also not a good argument for compromising the game with a change in net size.
With regards to Dryden's other comments about goalies never getting to their feet (ie. remaining in butterfly and relying on backside pushes or RVH pushes off the post) I believe he is totally wrong. The butterfly and related equipment designed for it has been around for well over a decade, closer to two decades, and goalies are still taught to get on their feet when the puck is more than a stick length away in the pie, and in many other circumstances.

@mossey3535 's recent posts about post integration, and
staying down too long.
There was an excellent thread on the old goaliestore forum about the King, and how he played deeper in his net allowing for more time to react to shots. iirc it led to failure, and a difficult adjustment period as Lundvist had to (re?)learn to gain depth.
As far as I was following the lastest in developments a couple years ago, in addition to concepts like head trajectory and quiet eye, the other idea was "the box" (not sure what they actually call it). The idea being that (assuming that the goalie is square to the puck) there is a box in front of the goalie that the puck
must pass though to hit the net. Because of angles, the further in front of the net/goalie, the smaller the box. So while goalies are taught to still get square to the puck in the shortest distance possible and then gain depth, the point is they are
still taught to gain depth, and doing it on their skates is the fastest way to do that. Doing it in butterfly using backside pushes like Dryden is suggesting is slower and opens holes.
The solution is not to make the nets bigger. The solution is to make better passes in the offensive zone (think late 70's/early '80's Red Army) and get the goalie moving while down. Take a look at Miller's power play goal against STL in game 1 of last years playoff, where Tanev and Edler were on the point, they were up 4-2 and just killing time on the PP, so they moved the puck around.
Or continue to allow crappy passing in the NHL, and make nets bigger.
