assume that we have a git repo per package, then the deps ( like qemu
?pxe etc ) could also use the same process ?

Also, would it make sense to consolidate this queue under the
github.com/CentOS/<package> repo ?

I'm also thinking that we might need a process like this for pretty much
everyone else - there isnt a precidence for the SIG's in this regard as
yet ( and anecdotally, we use a more manual version of exactly the same
process for handling branding/blacklists in the centos distro rpms queue
as well ).
