So why is it a great idea today?
Nicholas can answer for himself but IMO the investigation has become so huge that there's a push to keep pumping it up more and more. It's a jigsaw that we thought was a 1000 pieces but now realise it's actually 5000+ pieces and we've not put all of them in place. The significant pieces have been found and added to the jigsaw. We can now see what is depicted and what's important. The pieces yet to be placed are like bits of blue sky in the top RH and LH corners which don't actually add to our overall understanding and appreciation of what's depicted but are pleasing to place as an exercise in squeezing every last piece into the picture.
This thing will go on long after we are gone and still people will be seeing missing pieces of blue sky and will hunt them down like their life depends on it.
