As an engineer, I would not want to work in a team that works the way you seem to paint as ideal here. Especially "don't expect engineers to do anything other than what is requested". Engineers and PMs are "partners in crime", they have to collaborate with their skills complementing one another, bounce ideas around to find the best outcomes. Many good engineers also have a good grasp of product. Having a mindset where it is always PMs "requesting" and engineers "deliver only what is requested" -- in such an environment I would (as an engineer) find a new job.
