This sounds like a good plan to me. The primary.xml file ends up being quite
large when looking at all the packages in a distribution.  I did a quick
test by running two versions of createrepo on the FC3 base packages - one
version creating the normal primary.xml file, and the other creating a
trimmed down version without the fields you mentioned.  The trimmed down
version ended up being about 25% smaller filesize (by MB, not by line
count).  I imagine that should speed things up quite a bit for tasks where
that information is not needed.
