Similarly, we might say: energy is a feature of matter, and have no problem with the units of energy. Does this make a difference?
But energy is not a "feature" of matter at all?
Kinetic energy is a feature of movement, And potentential energy is a feature of distortion of spacetime (or if you don't like GR its a feature of gravitational seperation)
Photons of light are not matter and they most definitely have energy for example.
So by trying to make energy a "feature" you are indeed making a random quality and your original statement was perfectly correct and I did not misunderstand or misinterpret it .... my answer was correct.
if you want to make something a "feature" of matter first show me an observation that shows it to be so other than that it is indeed a randomly chosen quality because we certainly haven't needed it in an science so far.
