Short answer: nobody knows! (yet)
Long answer: probably not (my personal opinion.) It's first and foremost a pack for the server. Things like creating ages and the like doesn't make sense because their stated philosophy is a desire to create a continuous world with other Mindcrackers, and to do more community stuff together than in the previous FTB series. It also provides an easy way out instead of making things like nether hubs, and transportation networks that Mindcrackers love to build. Finally, it makes the game easier (especially with dense ores) and they seem to want to take the hard route.
