This opinion was based on the memory of a time when routing table size
threatened to exceed the maximum capacity of the routers of the day, and
would have exceeded this capacity without the introduction of CIDR and
strong aggregation.  Once bitten, twice shy.

So we are left with a legacy that strong aggregation is good policy, and
our addressing allocation requirements are substantially based on this
policy.

We don't have such a problem with routing table size these days, but the
engineering point was made and is still valid.
