PMs spending too much time on specific features is the key reason I advocate for problem-based roadmaps rather than feature roadmaps. All data points and feedback is often retrofitted as support for the initial feature solution (aka the feature you thought of first) rather than being used to diagnose the underlying problem.
I wrote an article about this at https://medium.com/product-managers-at-work/the-product-road... if you want to learn more.
