I mean, in the universe of Naruto itself those certainly aren't the "mid-levels." All of that stuff is thrown around pretty much exclusively by S-rank ninja. But in a cultivation setting that doesn't have to (and really shouldn't) keep the distribution and levels of powers exactly the same, yes you have a point.
Hell, the easiest and most basic of all techniques that every ninja graduate has to learn are 1.) instantaneous replacement with a nearby object, 2.) physical transformation into a similarly-sized person or even object, and 3.) creation of illusory copies of yourself. That's the Beginner's Package literally everyone gets at the start (except for Lee).
