What's missing from the commit message is why this needs to be a flag that userspace needs to enable,
instead of something that only counts as an informative query.
I gathered from danvet that blindly exposing things breaks existing userspace, so could that information be added to the commit?
Also missing IGT tests, would be nice we at least get some verification things work as expected.
