By definitions trim is a secondary flight control function. Maybe current flight training should focus more on actual flight skill rather than system management skills.
"Primary" and "secondary" are abstract labels that don't do much more than simplify and lay out the basic scheme for new students. But I was trying to foster a discussion where we talk about actual flying technique. I.e., what do you
do, not what you
call something. That's why I laid out examples. Your post addressed none of that, it might as well have said "the elevator is Ozzy Osborne and the trim is Axl Rose," and would have carried the same amount of meaningful content.

The CRJ does; I don't know how strong the tendency is compared to other types. I'd be curious to learn.

That's why I tend to stay away from abstractions. A phrase is said, to mean one thing, and can be understood to mean a whole lot more than the speaker intended.
