Also, you may no longer use the "go against the grain" method in choosing HS or College, because you won't know.

Not really true, though it is much fuzzier now.  You can still see the overall averages for the world, but not by individual teams.

For example, in Coop, I can see that the average draft scouting is COL=10, HS=7.  So I could still "go against the grain" if I went heavy in HS.  But what I can't see, if I were picking 10th as an example, is if 7 of the 9 teams picking in front of me are heavy on COL or not.
