Why should it not have this option?
It would not be very nice of Apple to say that in Final-Release, there is o need to start up in 9 alone.
There are some programs that won´t run under classic even in final, i.e games that run on rave in OS 9. These games run under classic, but with really low frames.
If this option is left out of the final, maybe I will be one of those who stick with OS9.1
