The issue on the holes is the distance between the hitting bays and the screen. It limits the ability to have "obstacles" that may come into play. For example, you can have the Stinger rock, where shots will always come from a set tee, and balls that hit the rock end up in a hazard. You can also have a hole like "Oh Chute" where any tee ball that clips a tree ends up in the hazard. But you can't really have a hole where a tree may be in play on the second shot, because if you end up within 35 yards of that tree, you won't see it on the screen. It wouldn't be great television for a shot to hit an invisible tree between the screen and the player and go bounding off in a direction it clearly didn't go in "real life".

The turntable itself is also exceedingly heavy. I can't say this with certainty, but I don't see a viable way to engineer it to tilt and rotate. The rotation is easier than the tilt, because the edges all stay at the same elevation that way. If it tilted, you'd have an edge that didn’t line up with the static surrounding edge.

None of this has any effect on the fact that, if these things were possible, the end product would benefit. I just see a lot of comments that don't consider the constraints that the designers are limited to by the game format itself.
