If it's not Heroku's fault in some partial way, then look at it from another perspective. It's an opportunity for Heroku's competitors in a market that is quickly becoming commoditized. At the very least it's a feature that I always look for when using pay on demand services, and will rank very highly on my list of important to have features.
Akamai comes to mind as an example of a company that has always had similar issues. If I ever were to use them in the future, I would have to factor into their monthly costs the partial FTE required to manage their usage and costs. More importantly, if there are other CDNs that offer better cost management features, I would almost certainly use them before ever using Akamai again, unless there was no other technical option.
