Yeah notably examples are given with their inverse functions. I’m pretty sure you don’t want that in a crypto hash ;)

Haha! :) No, not overall, but you do want reversible steps in a crypto hash as Reversible steps make better mixing functions, Because you’re not losing information so you avoid iteratively diminishing that information leading to a smaller state space, and more state collisions.
Keep in mind that there's a big difference between cryptographic hash functions and the kind of hash functions investigated here.
