"We’ve received an indication, from somebody with the experience to know, which suggests that the reason could be because – on the new XGS-PON network – Virgin Media may struggle to conduct monitoring of their network / Hub when Modem Mode is enabled. At least on the nexfibre build, VM don’t own the Optical Line Terminal (OLT), which makes implementing a solution via their wholesale arrangement a bit more complex."
This seems a much more likely explanation.
