Absolutely.  The problem stems from inadequate foresight on the part
of router vendors and providers being unable to sufficiently influence
router designs so that the needs of high end providers are met.  There
isn't a whole lot of viable choices at the high end.

I fully agree.  It was one of the last things considered.

Quite a while ago on this list it was pointed out that address leasing
and coerced renumbering (its coming down to forced) was something we
wanted to prepare the community for but that we were hoping to avoid.

It might be that better routers and/or better methods of configuring
aggregation help take some of the pressure off and change things back
from "forced renumbering" to "encouraged renumbering".  That hasn't
happenned yet.

Tony Bates used to do this and send it to the list.  Its not as if no
one has thought of this.
