Sure. That also implies the importance of S-box quality assessment.

My approach was to generate a random S-box and let the user change it
if it performs badly.  But that's a sort of responsibility shift.

It's time for me to learn a bit more about S-box design and verify that
the specific S-box has no obvious defects at least. :-)
