What, like a secret shadow repository that you move the objects into?

That could be very expensive in terms of disk IO if those objects
are in large packs.  You'd need to break the pack apart into the
"ok" and "sekret" parts.  Ick.

See my recent email (like ~10-15 minutes ago).  It will be rejected
due to the issue that unreachable objects are subjected to GC and
you'd easily see your repository delete that data on the next "git
gc" invocation.  Automatic data destruction is not something that
users come to git for.
