No rule is inviolate
Just a side note - one thing that's almost never taken into consideration is that most armour has two effective "weights" - one when it's being worn and another when it's being carried....
That'd probably factor in to carrying capacity. While there's a spot on the body to wear armor, very few will pack nicely into a backpack/pouch, and probably would have to be carried in the hands otherwise if not worn. None of this video game stuff where you load up on 6 suits of enchanted plate mail and sell it at the vendor later.
