Exactly, we can use it from the kernel and most of time it is of no-use.

I added this enabled by default so we can backport it to Dunfell (as
it won't change the current behavior). For master, we can turn it off

I'd like to get this one merged first (and send the backport request)
and then I can send a patch to disable it.
