Nobody's bikeshedding anything.... Heroku have admitted it's a real problem, they have begun addressing it and increasing visibility and awareness into it. There is no news or data being added at this point, it's just RG retelling the
exact same story.
And the story includes an application where visible parts of a second are used to construct their pages one very slow request at a time (regardless of what Heroku adds) which is interesting for a lot of us because that's not how many other platforms work.
