We could do so, should I provide a proper patch?
On the other hand I think this approach is a workaround to circumvent
the MTD architecture flaws mostly needed in embedded systems where we
control the whole environment. Should we really introduce this switch to
the whole bunch of users working with mainline distros on their beagle
style HW?
I think the user space tool approach is more useful there.
