Now you shift the goal post. We were talking about secondary stats.In the TSR era Dexterity was nothing like as overwhelming. For that matter in the 3.0/3.5 era if you were a dex-type you couldn't drop Str at low-medium levels; you didn't come with Weapon Finesse and ranged damage used Str.
And in the 4e era Int would cover for Dex on the saving throws and AC (and Cha for Wis on saves). So Dex was marginally better but only marginally.
5e is the most dominant Dex has ever been.
And dex and con were very important in AD&D. Only fighting types needed strength. Others would only get +1/+2 for hit/damage at most.
