The bigger problem is the weight limit, on the stream, Sven's character was unable to lift Gale weighing 65 kg at 17 strength.
I'm not sure how much the BG3 goblins weigh, but I'm betting around 30kg.
Speaking of weight...
The skeletons weighed 20kg.
The weakest possible character with 8 Strength can throw any enemy weighing 24kg or less at their leisure.
I'm concluding that under this system a level 1 character with 8 Strength can throw any skeleton, perhaps a level 20 lich, into lava, a river or a bottomless pit with a 100% success rate. Seems perfectly balanced.
