At first glance seems like the last category would suffer unless someone was "on the bench".
When almost a quarter of the company (15 devs) can both see and feel your contribution to make their lives easier and more productive, you've got a pretty strong political position even if you aren't directly producing product. This is true even if you produce, say, an internal dashboard: you're known as the one dev who took time out to help the 20 sales people sell better (or whatever); you know their names, and they know yours.
