It's what I tried to address in the second part of my comment. A lot of teams don't have dedicated PMs in the first place, but for those who do get those jobs there's an extremely wide and well-distributed gamut of competences and skill sets, even more than developers I'd say. And you have to figure out whether you got a proper one, in which case it's the right thing to run such tasks through them when non-trivial, and then there's the rest. It depends on which market bubbles you've worked in to determine whether this latter group is an outlier or the norm.
