Actually the backend code has been rewritten and this is the way it's 
done now. I think that the larger file size is a non-issue for documents 
that end up in professional print (esp when images are also part of teh 
document). For documents meant for reading from displays font expansion 
makes no sense anyway (actually, in print it also is somewhat debatable 
as abusing it makes things worse).

Btw, as font expansion works on a line basis, having many more steps 
does not make a big difference in file size (contrary to having more 
font instances) so there you gain. Also, you might consider applying 
font expansion in selected cases.
