you are correct "as built " is just that, you do not have control, but it should influence a decision to buy, hold or sell.
I don't recall ever considering TT length in sizing a bike back in any shop I ever worked for. Stem length was used to compensate for any perceived shortness or longness. Weird for you. Works perfectly for me.
Be that as it may, the bike has been bought, being held, and most definitely
not being sold.
