The thing is not invasive, so backpatching is a low-risk move. We can
as well get that into HEAD first, wait a bit for dust to settle on it,
and then backpatch.


I would definitely suggest putting it in HEAD (and thus, v10) for a while to get some real world exposure before backpatching. But if it does work out well in the end, then we can certainly consider backpatching it. But given the difficulty in reliably reproducing the problem etc, I think it's a good idea to give it some proper real world experience in 10 first.
