obviously if you can do the math correctly the bankroll you need to play different limits is going to change according to your winrate etc. having a 10 bi role is fine if you move down whenever you get down to 5-6 bi's. I think if a change were to be made to the FAQ, it should include some of the math and the fact that bankroll requirements will change as you move up, but also keep the part that says "as a convention people usually say to keep 20bi's to the limit you want to play."
