personally i feel like 'mundane' is better used as a descriptor for the nature of a kind of action rather than a...scope or grade of them, even if your 20th level fighter is reducing a castle wall into fine rubble with a single punch, well, a punch is still a punch, it's a mundane action, albeit an extraordinary example of a mundane action, that 20th level fighter is still just doing mundane actions and is therefore still classified as 'mundane' themselves(barring deviations of individual subclasses), it's exaggerated well past what would be possible in the real world but it's a logical extension of everyday actions and what would be possible if you removed the 'skill cap'/physical limitations of the real world
I (obviously) tend to disagree. If you told me you were telling a mundane story, then the protagonist threw a punch (mundane action) that shattered a hole in space-time that they then reached through and dragged (mundane action) their grandfather into the present day... that isn't mundane. Sure, punching is mundane and grabbing someone and dragging them is mundane, but punching and moving them through time is not mundane.
Or, to take another example, running is a mundane action. The Flash capable at running faster than concepts, is not a mundane character. All he is doing is, technically, the mundane action of moving, but when you can move faster than the concept of death itself... you are doing something beyond the mundane.
I think your extension comes from the idea that there are "supernatural" things which have no actual real-world mundane action equivalents. But I have a hard time with that assertion, because the sheer number of fantasy stories I've read have shown me many types of "magic as physics" types of situations, and so there are very very few things I would say could not be equated to mundane actions if the cap was non-existent. It is much more useful for me to look towards whether or not the scope or degree of the action is mundane. Throwing a punch that breaks a normal man's nose? Mundane. Throwing a punch that leaves a perfect imprint of your fist in a steel plate? Likely not, but maybe. Throwing a punch that catches the air on fire and sends a flaming lion's head blasting into a man and throwing him off his feet? Supernatural/Extraordinary/Not Mundane.
