The simple solution is to save the file in "Adobe Illustrator 1.1
compatible format" or whatever the button is labeled in the dialog box.
Then the prologue is very short.

The bigger problem with subsetting the prologue is that you can't
interchange prologues between documents or to factor them out (one
prologue is downloaded, but 100 individual illustrations can use it).
We started out with the idea of subsetting it, since it gets pretty
big, but kept running into difficulties.  I think it still makes sense,
though, and I will re-enter the suggestion into the Illustrator tech
group.
