Yep, I was planning to add it in a newer version when needed, or post
it seperately after this series.

For this one, actually that's why I wrote this patchset. However, it
does not mean that I think we should have it. I was just trying to
post this out, to see which one we would like better. For me,
error_report() with an exit() is good enough. So, if we are obviously
liking it, I am willing to continue maintain this series until it's
merged. Otherwise, I am still okay to put this series aside if we do
not have a very strong motivation to do the change. :)

Thanks for reviewing!
