What Nico said.

More importantly, ones who are not confident with git would not
be able to resurrect unreachables that are left unpruned anyway.
The unreachables are by definition not connected to anything, so
they cannot do much better than grepping through droppings left
by "fsck --lost-found", which they probably even do not know how
to do yet.
