Those cases can be solved with 3 sledges which is good enough, those shown just have nice algs and recognitionI know Sarah advanced.
I think I have to rephrase what I wrote.
What I actually wanted to ask is "Are those 4 Z Conjuga excluded because the U perm appears in a good angle whereas for the other 4 (which are included here), you have to rotate to solve the U Perm?"
