Not unless you are going to implement proper instancing and those lacking netlinkingrules into Alcugs. (Yeah, I know. I am always nagging about that)
To be compatible with MOUL Alcugs needs public ages, sub ages and child ages. And although I would rather not see those neighborhood instanced child ages back, they are still part of the protocol.
With sub ages however you can do very cool things so I really want support for those. First of all they are correctly instanced and can be shared without the need for book sharing (think Delin, Tsogal or the Er'cana silo). Secondly you can change sdl variables in sub age A while you are in sub age B, and you do not need to own any of them (have them in the AgesIOwnFolder). This means you can create interesting cross age multiplayer puzzles.
