Inputting a special move or super after a pushblock is significantly easier and more common than actually timing it to get some frame advantage, which is what I think actually qualifies as a pushblock guard cancel (Hence the cancel)
Currently it shows up a lot of times where I think it doesn't seem "deserved" or notable, like pushblocking an opponent away from you and then throwing a projectile at them.
When I attempt a pushblock guard cancel, I want to know if I managed to reduce my blockstun, not if I managed to input a thing after pushblocking.
If you have a special effect for something, surely it's better to use it to indicate a special case than to have it show up fairly commonly, with the special case being almost impossible to distinguish.
I might be alone in thinking this, in which case I concede I guess
