I think you're correct.
I originally dug in my heels, because I was a IAS/VS guy. It's smooth and I don't like tossing granny out of her seat. I eventually liked Vnav on the 88, using it all the way to g/s intercept. I liked the challenge of making it smooth and precise and efficient. I never liked being told I
should use it, or being critiqued for not using it.
On newer types of the MD series, which should be arriving within the next several months, you'll find this "requirement" no more - once inside of the terminal area, lose the Vnav (PROF) and use v/s or IAS (Level Change).
This short film clip demonstrates selecting V/S or IAS, and that Vnav is relinquishing control of the airplane (courtesy McDonnell Douglas):
