I wouldn't go by sheldon brown when it comes to fit advice these days.
Also, I didn't say that KOPS was the only way to do things. More and more endurance riders are moving their cleats back as far as they'll go to take the gastroc out of the equation as that's most prone to fatigue the earliest. There's a range of what works.
I also said "You position a saddle with regard to KOPS or however you feel that setup best suits your body." So you may want to read completely before commenting!
Regardless, reach to bars is secondary to where your ass is going to end up and how high up that will be.
Are you suggesting that reach takes precedence over where your knees end up? That makes zero sense to me.
KOPS is an artifact in that it's a holdover from old pedal interfaces. Just because KOPS isn't the solution doesn't mean you don't need to start by figuring out where your knees should end up.
