I would be loathe to uninstall G.Fast even if it were no faster than VDSL2, because of G.Fastís greater technical sophistication. I wouldnít want to lose SRA, and going back to VDSL2 might mean losing vectoring and even G.INP depending on the VDSL2 cabís capabilities. Is that correct?

I'd be torn, as 20Mbit upload is certainly very useful but then realistically if the choice was 120/10 vs 60/20 I'd probably go for 120/10 as I download a lot of games.

This just feels like a fault, the fact it was iffy at the start, then the engineer fixed it for it to break again yet GEA test says its fine?  Something doesn't smell right, bad line card or bad modem perhaps?

I'm sure I read somewhere that G.Fast engineers were meant to uninstall the service at install if minimum threshold was not reached?

Yes but  I believe the minimum is 100Mb, reduced from the previous 120Mb.

Considering g.fast uses frequencies above the VDSL2 range though I'd kinda expect that any line able to sync at all on g.fast should be capable of a full 80/20 on VDSL2?  Unless there's some serious interference going on.

Some cabinets have over 500 VDSL2 subscribers, with no Vectoring.

I originally assumed anyone who couldn't get 80/20 would be stuffed for G.Fast and said so a few times and for the majority this is the case.
There are a few examples though of users hit bad by VDSL2 crosstalk in particular who only get around 60Mb but get 150Mb (or even higher) on G.Fast.

Considering now my current line is back to 80/20 but my second line was 66/18, not sure why my brain didn't make the connection.
