It's not the sole reason not to do...no no no. It's just that anything that EXTRA that manipulates the way the current points are done is an added level of difficulty IN DESIGN AND IMPLEMENTATION that makes it more difficult moving forward. If you're not already a wargamer when you enter this game it has a large learning curve with all the options already; I am seldom in favor of not doing something just because it will make it "easier for beginners". That's not a problem for me either.
For a game with little to no real errata, no bannings, and still some room to grow within the current context, it would just be a shame to have to veto new ideas in the near future based on releasing something like this too early.
I love the idea overall but think it either needs to fit within the already established rules of the game (titles/crew/upgrades) to be released at this time (or any time soon. ~ another year) or wait until options are running thin to introduce a new way to manipulate the current, generally balanced rules. And do it because it improves some lacking part of the game or increases options... not just for fluff or because it would be fun/cool.
