Conqueror of Cacoons
That is true. That would make for interesting gameplay because if at that point you can't build that many troops you won't use it but if you are a powerhouse you would be able to construct and maintain such massive armies.
Also, I find there is a larger rift in 1upt vs. stacks in civ 5 people that civ 4 because quite a few civ 4 fans absolutely hate 1upt but civ 5 fans may like the game but dislike 1upt, or love it.
