Something similiar to a global hotspare.
if Gluster detects some SMART issues (lot of reallocation, predictive
failures and so on) can
bring the hotspare in action, starting to replace the almost-failed disks.

If disk fails totally during the replace, healing should start from a
middle point and not from start (as some data were already synced
automatically) by using the "spare" disk as automatic replacement.
