The different label to differentiate between locally used ULA prefix(es)
and the remaining ULA space is intentional.

Using different first hop gateways for GUA and ULA is another
problem.  It would be nice if hosts would (optionally) not consider
a gateway announcing a ULA prefix as default gateway, but only for
ULA reachability.
