They have to, else Prof X doesn't HAVE a team to fight evil with. If the movie opens and they're gone and some randoms are at the school instead it's going to be very jarring. The actors are available, NOT signing them is going to look very, very bad. It'd further emphasize this feeling that this is really X3 the Bryan Singer Cut: take away all the characters that don't have an older version in the future ("his" timeline).
