I've just upgraded my PN FTTH from 40/2 to 80/20 and in both cases my modem profile has matched those figures ie the advertised maximum. Currently I have my Router/Modem in the room where it's connected to an NTE5 which BT changed on their own accord after an engineer callout in regard to a voice fault a few years back.
However the location where Router/Modem placement would be physically more suitable is served by a contract type BT socket which was installed by the builders and the same as the type the NTE5 replaced, but is the slave socket.
I assume it is still preferable to connect the modem to the master BT socket, but is it such an issue as it was with some adsl setups? I would estimate the distance between the NTE5 Master to the Contract BT Slave socket to be around 10 metres.
