Yeah.
Didn't really think about that one, but if distro's want to change and
adhere to it, that would be the simplest solution
Machines that pin something should probably also use weak binding.
Conceptually it is probably marginally less desirable than a solution
where local.conf has *always* control.

What do the distro's think about this?
