Actually, no. This is exactly Google politely telling him that the particular request is a low priority. Unless you FR meshes with an existing roadmap item OR it is causing a significantly large business impact for an Apps Premier customer OR it is novel & potentially profitable and they humor you, it's not going to happen. Scalability is important at the scale of 200 million users, and going after the edge cases doesn't make good business sense.

That said, they do take FRs seriously, and they are incredibly (astonishingly) open about their roadmaps... depending who you are.
