     As co-author of the initial minimal.iso shipped by CentOS, I've 
always considered the current minimal ( which mimics the DVD "minimal" 
option and bundles all @base ) way too bloated. Personally I always use 
a trimmed down version of the minimal-C6 kickstart which I have uploaded 
to nazar.karan.org ( along with other useful kickstart files it used to 
be available at https://nazar.karan.org/tree/bluecain.git).
     Incidentally the ks I use for servers includes %packages --nobase

Let's trim the current minimal to what it once was and call it "micro" 
:) However I am not very keen into not including yum and 
openssh-{clients, server} unless we also provided a script which brings 
those easily for those needing them. And I suggest that because 
installing all yum deps via rpm is a bit tedious.
