Crazy Track and Mainline are aimed at two different markets, Mainline is very much modern 750/760mm gauge track and is very good, code 80 is just fine for that, also it competes with Tillig which has the looks but isn't as robust, and Roco which has good plain track but not so good points.
I'd agree that Crazy Track needs replacing with the "code" 55 rail, though, it was brought out in a time when pizza cutter wheels were the norm, but with modern RTR we don't need the rail depth and the rail height is far out of line with most modern heritage narrow gauge line which use far lighter rail. There's a couple of layouts going round based on the Welshpool which use code 40 and it's amazing how much better they look. Even the code 55 would be better than code 80.
Can't see it happening any time soon, though.
