Flash CS3 – no excludes, no intrinsics, no anything

Juten Tach,
i know, i am lightyears behind, but i just found, that Flash CS3 for Flash 9 projects does neither support intrinsic classes nor _exclude.xml files nor anything the flex sdk supports. I can’t believe it, this is …. i don’t know, my english is not good enough to articulate, how bad i find this.
I thought, i had found a bit of light, when i read, that you can use .swc (those being created with Flash CS3, not with flex 3 sdk, of course …) files to exclude classes. Unfortunately this does not work with symbols in the library, that link to a class, that you want to exclude.
grrr, i can just say, arghhh …, why is there no update for Flash CS3? grrrr.
