I think what bothers me about is the "no" and "change" part -- "change" is a verb, so it comes out sounding verb-like and we end up tacking on "feature" to try to make it a noun again.

While I respect the feelings from native speakers, Google told me that `change` can be a noun too. For the `no` part, may be we can use the term `less`? So that the feature name become to `less transitive change`, which may be more precise since there should always some changes are transitive.

> "no-cascade" feature?

I didn't know this word `cascade` before. I think it may be appropriate after I searched it. I can replace with it if we're happy with that.

> "isolated BMI"

`isolated` may not be accurate. Since the BMI still depends on other BMIs.
