Maybe it doesn't need "managing", Oren might just want to talk with whoever was responsible for the change and see what the best way forward is. I don't think panicked, knee-jerk reactions like "OMG we were wrong and will revert that commit pronto!" are beneficial in situations as complex as this.

You're assuming that the change was actually made. Until we hear definitively from Heroku, the only evidence is an (admittedly, well documented) blog post.

Yeah, absolutely. I'm just saying we can't expect a to manager to immediately respond to a highly-technical issue questioning subtle changes in internal behaviour which might have been introduced years ago.
