Well, the purpose is to illustrate the desire for the ability to have more than 3 ages in the game. While I do intend to create such a mod, I'd like to see the ages themselves become extensible, and I felt this would be more appropriate a place to request such a thing than to clutter up the Mod Wishlist with several huge posts, since I'm currently formulating the directions I have in mind for a 5th later-than-Late age, and will post them when it all comes together. Worst come to worst, it's atleast fun to share ideas and perhaps get some feedback on how others think pre-and-post ages may shape and be shaped by what's come before and will come after them. It's kind of a Dom3 speculative sci-fi
