Agreed. There is a role for a good manager to filter ideas from the business side and make sure all asks are building towards the products future. If the funnel is "sales people => engineers" you're likely to get a lot of spurious development that doesn't make the product better.

Reminds me of the "if apple built every feature requested" meme.
