I don't think "no config changes" is a completely black & white rule. The most important part of it is that you don't change the semantics or default values of any existing config options in stable, because that would cause a change in behaviour for existing deployments who upgrade. If backporting a bug fix involves adding a new config parameter I think that's broadly acceptable, provided the config option does not result in a change in behaviour upon upgrade that violates the stable tree requirements.
