Agreed -- I also see the argument for not diagnosing it by default. Normally I wouldn't suggest such a thing and I would not consider this to be a precedent to be applied to other extensions if it does get warned on by default. (I think the only other extension that might maaaayyyybbbbeeee be in the same category would be nested functions in C, but I've not spent nearly enough time researching that one to be sure.)
