Because it’s a waste of effort and money, the focus is FTTP. Nobody is going to trial something that in the best conditions on a short line delivers about what a decent 4G service manages. We did Gfast, it was accepted as a misstep, we’re finished trying to be innovative over copper.

What about a shift to the Profile 35b which is designed to make full use of the line without any presence of PSTN.

Ain't going to happen, legacy product just waiting to die.

Yeah true. I thought fibre was still some time away and copper was still being focused/developed on but seeing as there's been significant progress to fibre deployment around the country it makes sense to focus on the next shiny new product.

Also bearing in mind that Openreach's competition is all full-fibre, bar VM. Which is also doing a lot of conversion to it.

I think it's not possible because of interference from exchange-based ADSL, so couldn't be considered until all ADSL/LLU is gone. By which point we'll all have FTTP anyway.

(The narrowband voice frequencies - 0 to 4kHz - are irrelevant)

Remember that Openreach didn't even deploy VSDL vectoring except in a tiny proportion of cabinets, so I think that gives you a clue.

There's no benefit for Openreach spending money on VDSL card upgrades or software licences. For people with no FTTP yet, they have no choice but to stick with Openreach anyway. For people who do have FTTP available, it's much better if they migrate to FTTP.

Dialup at best was 40-50kbit/s using the 300-3.4khz range. No one would notice the difference.

I assume the switch from FTTC to SOGEA can be done in the background and isnt something an engineer is required for?

Yes, on the day of the migration you move your telephone from the socket on the wall to the socket on your ISP provided router. Dial tone may or may not remain on the wall socket.

Ah right so if you dont have a telephone no change to current setup really
