Signal quality is much less of a problem for VM's network, HFC is
expensive cabling, but lovely.

Not really - no cables and very few UBRs are 'black' (at their limit
at peak times), and these have their load 'split' (reseg'd) pretty
quickly.
No part of the VM network above the cable is ever more than 40% busy,
(for redundancy) until it goes off to transit or peering provider(s),
and/or the source of the content itself :-(
