There wasn't any room in the little envelope.
Seriously, if Resident Evil should stay the same in every single game, it would become repetitive and therefore lame (just look at Call of Duty). Resident Evil is still a great game, and if you're not willing to accept new things, you'll just become a scumbag.
Seriously, "Where could Wiggler's second segment be?" or "Don't touch lava, it'll burn you!" is NOT advice. Why even include that into the game when she almost never gives you any real advice?!
"I've never done anything like that before!" "Anything like what before...did you like it?"
