Just because it was built that way doesn’t mean it’s not discriminatory. An aircraft being half a foot larger wouldn’t have been a big deal if they were built to accomodate tall people in the first place. 6’2 is not an uncommon height.
But there is a pretty big difference between accommodating 93 percentile for men and 99.96 percentile, and that's only 5 inches in height between 6'1" and 6'6".
You know that how exactly?
Maybe that the case but if it’s not maximizing safety and minimizing failure risk (so by extension any unnecessary complexity) should be prioritized over any accessibility concerns under any circumstances
