The resource loader debug mode should set "must revalidate" NOT something like: Cache-Control: public, max-age=2592000, s-maxage=2592000
This is a good idea, but it needs to be only enabled on development instances, otherwise this could destroy servers quickly.
Fixed in r75827. I don't think it's that bad to do this in production because must-revalidate doesn't mean the client will pull the resource again every time: it'll just 304.
