I'm not sure what you mean by opt-in.  It's already opt-in in the
sense that users have to set $GIT_DISCOVERY_ACROSS_FILESYSTEM to
enable this logic.  Or do you mean that
$GIT_DISCOVERY_ACROSS_FILESYSTEM should not implicitly enable this
logic, but it should be controlled by a new dedicated variable?
