There are, and often times they're stuck in a loop of presenting decks and status, writing proposals rather than doing this kind of research.

That said, interpreting user feedback is a multi-role job. PMs, UX, and Eng should be doing so. Everyone has their strengths.

One of the most interesting things I've had a chance to be a part of is watching UX studies. They take a mock (or an alpha version) and put it in front of an external volunteer and let them work through it. Usually PM, UX, and Eng are watching the stream and taking notes.
