The "average" attenuation is sufficient that VDSL2 from the exchange, along with issues around interference mean it's not very practical.  VDSL2 is a "cabinet" technology - ie.  FTTN style of thing where you place the active equipment within 1km or so of a house.
Giving those of you with actual experience in getting this stuff
approved no real incentive to do so.

I take a bit of offence at that.   We tried very hard.  One of my engineers was on the Comms Alliance working group and put in a great deal of time with this.   There were many attempts at compromise to get it approved.  In the end, we could have had it approved (ie. unanimous vote) but in a way that would have meant a lot of forms of access would have disappeared (ie. no SHDSL, no AnnexM and poorer ADSL1/2/2+ from the exchange).
