It's an interesting problem. I used to work for a PCO.
A lot of developers do a really shitty job on the wiring, which is often why in these exclusivity agreements the PCO also negotiates to do the in-home wiring themselves. But these properties were built 10, 20 and 30 years ago when utilization was a lot less and infrastructure simpler. Often these contracts are not renewed (aggressive price competition from the incumbent provider) so it's not cost effective to do any upgrades until contract renewal time.
Then you have overutilized nodes and shitty service.
