See bug 1639237 comment 15. It seems it would be a useful thing to do, but it may be tricky to not make the warning very noisy.

Just adding my two cents, you have something similar as opt-in for "uninitialized property access" which is also extremely noisy, but in my opinion very very helpful for catching simple mistakes that might otherwise be hard to spot. I wish more browsers had that!

So, personally, even if it was just available as opt-in it would be a hugely valuable debugging tool for me. Although I realize very few projects interact with iframes in intricate ways, so it has a rather limited target audience.
