To be honest, given the fact FTTC at my cabinet was BDUK funded I wasn't expecting it to be viable for G.fast in the first place. Though it must have been, and I am pretty sure the FTTC cabinet has hit max capacity at least once (unless it was some weird database error).
I'm in no rush for FTTP, and I don't think OR would be in a rush to do it here anyway. G.fast has been very, very reliable and stable for me; the horror stories floating around do not represent my experience, which has been virtually flawless.
