As was discussed before

Tejun has a patch in the queue which exposes the HPA and real sizes to
the OS

Libata can support revalidating a disc

Once the HPA/Real size data is there the tools can be tuned for this and
a sysfs node added to switch hpa on/off per disc. At that point this can
be done by the user space intelligently.

The fact this is a user parameter is itself a problem.
