I'm posting this having just finished the 1,000 piece Underground map jigsaw, which has A LOT of white blanks.
This map includes the Overground lines forming an "outer circle", plus Euston to Watford Jn, ELL to West Croydon, Crystal Palace and Gospel Oak - Barking. The latest version which I've seen on line adds Liverpool St to Chingford, Cheshunt and Enfield Town, Romford - Upminster (Overground) and also the Liverpool St to Shenfield section of Crossrail (Elizabeth Line) and Croydon trams.
There must be a limit to what can be added in terms of clarity. Is it intended to add the whole of the Elizabeth Line when it opens? Surely you can't extend the map to Reading, but if the criterion is based on TfL ownership or concession, then that would be logical. A TfL takeover of the Dartford lines is still a possibility. I suppose Harry Beck would still recognise his handiwork!
