A good PM saves work for the team by shifting work away from from valueless investments. If a team is "slowing down to appease a PM" then that PM is worthless.

Knowing what’s valuable and what’s not is a function of being an employee. Designers and engineers should know where value exists.
If they need a PM to shift them away from valueless work, then I highly question their efficacy as an engineer. I also highly question that organization’s management structure and communication.
