But there is nothing stopping them splitting that single fibre going into the home by 4 (like the Splitter Node, but only split by 4) and putting them into 4 ONT's, that way its using the same single fibre.

Optical power budget. A 4-way splitter in the home will cut power by more than 75% - halving each time for the two splits then a bit of insertion loss.
It's a bad idea from the scalability point of view.
Ok, fair enough, was just a thought, TBH I never looked that much into it.
At least some of the spare fibres could be used instead of blowing more fibres.
So in our case here BT would just need to connect up one of our spare 3 fibres to the DP and a cable to one of the spare 3 fibres in our CSP, then through the wall to a new ONT.
Not that we need it, the 110Mbit upload will be fine for us here for a long time.
