Agreed. I think the most underrated feature of PON is the ability to run future generations simultaneously on the same line, without any impact at all to the existing install. The bandwidth on SM fiber is so enormous it will pretty much always (for my lifetime at least) leave other wavelengths open. This allows for deploying 25G-PON on the same fiber as existing 10G-PON with no negative impact to the existing customers. That's huuuuge in terms of long term operations budget and upgrade logistics.
