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.
