I thought I emphasized the point pretty well: Get involved in the process if you're managing a team of developers and don't just look at metrics. They can be misleading if there is no way for developers to communicate UP to managers or if there are self interested parties between you and your devs.

I've never thaught about a PM that isn't "involved" and only relies on metrics.

My experience is that PM's are part of the team ( and mostly a senior developer), not part of management.

They translate management decisions to their team and take responsibility for it. They shouldn't live in their ivory tower and not know what is going on.

Their experience gives them insights in developer efficiency issues and can solve more advanced problems.

Sometimes they help program, sometimes they are doing infrastructure ( Eg. Cloud management) or deployments.

They did good in the past and now do something else as a way of promotion and encounter new social aspects in managing a team and deploying a project.

Some should better stay developers and some like the challenge.

And if I interpreted the OP well, he's a promoted developer close to the team. And not a hired worker that thinks he's a PM without Dev experience.

Oh, we've had very different experiences relating to project management! I've never had a PM that was a former developer, and in my world senior developers usually act as solution architects without the title, mostly removed from the day to day development tasks unless they're briefing developers on documentation and implementation details.
