In general, I'm pretty against this kind of monkey-patching if it's made available to out-of-tree consumers. We should learn our lesson from XPCOM and recognize what a royal PITA it can be when extensions start to depend on implementation details. Allowing something to be modified/overridden by embeddors should be an explicit decision, rather than the other-way around.
