Actually, in a 2-rail situation, you get wheel drop on larger frogs because of the space involved, the rail height, and the flange depth. With a larger Ross turnout, you do get some wheel drop even with hi-rail flanges and, like prototype, the flange rides on the base of the frog. We put the frog point in because some members run 2-rail cars and/or locomotives with smaller flanges. On the #8 curved turnout, we actually had a couple of hi-rail cars derail, so we knocked out the wheel drop issue entirely with the moving frog. There have been a few articles on making a "flying wing" turnout and (in theory) you could make a spring frog that's closed on the normal state, but springs open when the turnout is thrown.
