I don't see any reason to only restore one node of your cluster.
That is the whole point of a replicated datastore. If you loose a node,
you shrug, replace it with a new one and go about your business.

But we expect something different in the case where a value was
updated and the more current value is available on other nodes.
Restoring an old value don't matter then.

Yes, but the same is true if you restore a relational DB from
backup :-D

Btw, this whole issue is not really Riak specific. It is

the system can
diverge from the rest of the system before you get undesired
results.
The 'eventual consistency' description makes you think the
system will eventually fix itself, though. But, won't you have a
similar scenario - and even more difficult to fix - where for
one reason or another you need to restore a backed up bitcask
file that contains items deleted after the time the backup
was done?
