Indeed, but your Initiative and ranged attacks - both important capabilities - will suffer for it.
Paladins and Barbarians are utter naughty word with ranged attacks anyway (and as pointed out, they're the two classes that really benefit from Strength). They have zero class features that assist ranged attacks (other than extra attack, but by the time they're 5th level, they're really trying to close to melee at all costs anyway).
If your Barbarian or Paladin is whipping out a bow, they've already lost. No rage bonus damage, no reckless attack, no smites, no Smite spells, rage ending without a melee attack, no advantage to Strength checks etc etc etc.
Rogues and Rangers are the Dex go to guys. Barbarians and Paladins are always better going with Strength.
Fighters can go either way.
Feature; not a bug.
