And I assume that getting the datasets is also the bottleneck for germline selection.

Incidentally, is this the sort of problem which can be significantly speeded up by money/publicity? And how much money? Is this the sort of thing which would be a good target for philanthropy?

You would have that data if a country like Singapore decides to do DNA sequencing for it's entire population.

If you want to go in that direction in the US you would need to lobby for SAT scores being included in the digital health system created by Obamacare.

Apart from that the cost of genome sequencing is an important variable. Developing cheaper sequencing technology will increase the amount of people who have their DNA sequenced.
