I tend to agree that "butt wink" is very overrated and very overstated. These internet coaches are always trying to find something to fix. I have this so called dreaded butt wink and it hasn't bothered me at all in the many years that I've been lifting. Keep the back mostly neutral, or even slightly arched, and you'll be fine.
