Except he hasn't built those yet...but yes, it would be awesome to have that three hole stretch released on its own once things are done...much like craig is planning to do with amen corner.
If the game allowed you to select the holes to play at run time, then this wouldn't be necessary (the old red chain software allowed you to toggle the holes to play or not play)...but it doesn't. This option would be great for online multiplayer as well if people only have time for a short round (just toggle on 6 holes to play or whatever). Hopefully it comes at some point.
