I remember hearing that Gavin wasn't around when I posted this initially, I don't know if he's back now but either way, does no one else have any interest?
I guess I could make it three-valued, ie. true|false|inherit, which would give you the behavior you prefer.
Add a feature request to JIRA if this is something you really *have* to have.
To be honest, if I'm really the only person interested in the feature I can live without it. Unless someone else feels like chiming in I can't see having you devote the time to changing it.
