By tomafro:

I had a bit of a chat with Craig about this on the old Campfire, and nobody came up with a good reason as to why slimmer does this. It's too early in the request cycle to actually remove most junk headers (such as those added by rack-cache). The behaviour seems to have been there since @techbelly's initial commit. I'll move the responsibility over to the router.
