Not really.  The point is that you've proposed something as an addition
to the kernel that can also be done in userspace.  Checking if it can
work easily there is like a barrier to entry.  If it works, then fine,
we're done.  If it throws up problems then we reconsider the kernel
route.

hdparm has full support for the SANITIZE commands in userspace.
