I think it is hard to build greens that sit correctly both ways, yes you could play to some with the green falling to the back...but how many times and its a chore

We've built many greens that sit correctly from multiple (4) directions.
Wolf Point wasn't built specifically to play in reverse, we did consider it as an option, and cross country golf is very popular with some of the semi-regulars.
The ultimate reason why we didn't build a reversible course was because the reverse would have had more greenside forced carries.
We placed the hazards behind the greens in most instances.
Lastly, Tom's experiences at The Sheep Ranch and elsewhere are probably similar, in that their greens can be played from multiple directions.
