I think the real interesting point is slapping the title of engineer/scientiest on to anything and everything regardless of the accreditation actual handed out. soon coming up.."cafeteria engineer", "janitorial engineer"...
The difference of course being that other types of engineers have to take a PE. The idea of requiring a PE to have that title is protectionism no different than limiting the number of graduating doctors to keep salaries high. No one will ask a software engineer to build a bridge - relax. Your protection racket is safe. Software engineer is a title conferred on someone who builds systems. It is fitting. And, if we're being honest, the average "job threat level" of a so-called "real" engineer is about the same as a software engineer these days anyway. With the exception of some niche jobs every engineer I know is just a CADIA/SW/etc jocky and the real work is gatekept by greybeards.
No one will call someone a cafeteria engineer or janitorial engineer. The premise is ridiculous. There is a title called "operations engineer" that uses math to optimize processes. Does this one bother you too?
