One thing I want to mention is that there's another difference (other than flexibility of the cable) with Cat5e versus Cat6 cables. Cat5e is rated up to 100 MHz, while Cat6 is rated up to 250 MHz. This might make a difference if someone is close to their g.fast cabinet to receive frequencies over 100 MHz. However from what I understand 'profile 1', which is just a little over 100 MHz, will be used initially. Profile 2, just a bit beyond 200 MHz, could and will most likely be used at a future date (like VDSL2 on FTTC was initially 8c and then later on was changed to 17a).
