     The kickstart is intended to create images which can also run on 
real iron, including those with "real" storage ( brocade, qlogic etc ). 
Therefore the firmware is left there on purpose.
     As of removing the firmware in %post: yes, it is one way to do it. 
But I find it awkward to install something just to remove it seconds later.
     As of ks file size: who cares ? You create it once and use it as 
many times as needed. An extra dozen or hundreds of bytes / couple of 
lines are not significant in this context

     And last but not least: You can always tweak the ks to fit your 
specific needs. This one is meant for an _almost_ minimal but yet 
general context. If you really want to go "minimal" there are at least 
other 5 packages that can be removed ( but this will, of course, remove 
some of the functionality , such as processing delta updates or selinux 
). If you want to go this road, even yum itself can be removed.
