Jimbo asks:
What's our exact policy on this? I'd be happy to issue a ruling, but I'd prefer to stick with exact precedent. But I don't remember what that is.

Last I checked, Jimbo had delegated the ability to make the final and binding decision to developers, interpreting the will of the broader community. Which I'm sure will be done in due course, if it proves necessary.
The most recent precedent was [[user:SH]], where Tim Starling made the final decision, after taking into account everyone's opinion.
