Because more than two relays per IPv4 address is ignored by the network; and
that was the whole point of the question.

I suggested some time ago that with the scarcity of IPv4 *and* abundance of
multi-core CPUs that the Tor developers should really consider raising the
relays-per-IP limit from 2 to at least 3 or 4.

Sure one can use IPv6, but I doubt there's any serious amounts of traffic on
IPv6 via Tor, so it will not help  with the original request to do something
which would help better utilize the full available bandwidth.

With respect,
