4e made the martial power source martial magic. It deemed some of the things in that power source as not magic in the traditional sense, which means those things were magic in a non-traditional sense. I.e. supernatural, but not magical.
"Martial: Martial powers are not magic in the traditional sense, although some martial powers stand well beyond the capabilities of ordinary mortals. Martial characters use their own strength and willpower to vanquish their enemies. Training and dedication replace arcane formulas and prayers to grant fighters, rangers, rogues, and warlords, among others, their power."
So 4e had it, but 5e had to be super simple to the point where they got rid of a lot of things that weren't complex and added to the game, like supernatural abilities.
