Also, the menclose element is used to draw something around/over an 
expression. So adding arrow notations would only be to strike this 
expression like in the cancelto case (one can still use "normal" text to 
draw arrows in token elements). The package documentation does give much 
indication about how this notation is used and how popular it is, but it 
is interesting to note the feeling of the author:

"Drawing slashes through math to indicate “cancellation” is poor design. 
I don’t recommend that you use this package at all"

So it does not really seem essential to add more notation beside 
updiagonalstrike, which has a concrete use case...
