While changing somethings name is a unique mechanism the outcome of the power, i.e. changing the state of the thing to another state, is still basically the same.
Ichibe changes what something is, yes. He performs a transformation of an object. However, he doesn't cause a transformation of a property as an abstract thing.
We want to go away from plantonic forms as explicit standard, but let me still bring them up here as an example. It is one thing to take a circle, name it square and by that turn it into a square. It is a whole other thing to change the platonic form of circleness and change what it means to be a circle-like to turn the circle into a square. The result might be the same, but it's archived in completely different ways, different things are manipulated and it behaves differently in relation to other powers.
Our ability pages can't handle all explanations, true. However, they should separate what is manipulating fundamentally different things. Otherwise, why even have them if you may as well just explain all power on the profiles and have people think?
You can manipulate gravity to make something float or you can manipulate the law governing gravity to make something float. So should we group those into the same ability and say "That's just two different scales of the same thing. Not our job to explain people that those are different"? Not a good take, as it just produces false equivalences and solves nothing. If it helps to show there is a difference, why not do it? Especially for a power like concept manipulation that many people have trouble wrapping their head around, making the "think for yourself" approach suboptimal.
If you think the ability shouldn't be listed as something different than concept manipulation, fine. But if you already say that it is a different scale (or that it is better than another application), then let's at least make it its own type. That's what types are for, after all. To represent different scales or natures in which an ability can occure.
