Sagat and Sakura are just different enough to not get labeled as part of the group, but even they come close.
When you have ALL of Marvel and Capcom's characters to choose from you don't want to go "Okay, let's put in karate guy and other slightly different karate guy." You want to go "Okay, let's have the karate guy and ... oh... how about the monkey man that rides the dinosaur, or the guy who's made entirely out of sand, or the medieval knight with the laser sword and the jet motorcycle."
Sure when you're doing your crossover game, you want to hit the A-list characters first, but once you've got them out of the way, you start pulling from the characters that are just going to be fun to play (and maybe one or two "How they heck did he get in here?" characters just to keep people on their toes.)
