Mostly because breaching dimensional walls is an EXTREMELY risky business. The only reason I know of this is because I was observing another dimension at one point. My counterpart there breached a dimensional wall to get rid of Sonic, but it caused the wall to fade COMPLETELY. The problem when that happens is that all dimensions adjoining that wall will collapse in on the newly formed void. Those dimensions are now... well, gone.

Not something to experiment with. Looking into other dimensions, fine. Breaching them - EXCEPTIONALLY risky.
