I am very much for any SWE or Eng. Mgr taking responsibility and spending as much of their time as they see fit on anything they see fit to build a great product. Not only that, but I will encourage them to continue doing so and give them a great review score and potentially a salary bump!

The duties of an engineer are to know what to build, prioritize it against their other work, and build it, alon with the other engineer in their team. If you consider the "knowing what to build/prioritize" as PM work, so be it. I consider it engineering work.
