Well, 5e rules do state that you must use a ranged or finesse weapon to qualify for sneak attack... but they also state that you may use either strength or dexterity for your attack/damage roll with a finesse weapon. So you could still make a rogue with a high strength and low dexterity, but you would not be able to use non-finesse weapons and sneak attack at the same time. Not sure what the use case for this would be, but its not impossible.
