Maybe... Just maybe they need to let those "shiny things" engineers leave if they don't like keeping things running and continually improving them after v1.0. If you only hire people who get bored with a project after a year or egotists who want to start from a green field on every single project, then this is the effect it will have on your products.

I think that's only part of it though. I think that the only way a company can let products wither for years without a single new feature or improvement is if they don't have a product manager to represent the users, and bring a vision to the engineering team.
