To me this isn't a "building" question, this is a "delivery" question. Currently the guidance is for the SIGs to own their dependency chain, and to ship their deliverables depending on things that are self-contained (or self-contained to CentOS-built content at least).

Currently there is a lot of EPEL rebuild activity going on to support the SIGs, and I think this is where we can make some improvements with the converged git structure. We, in general, want to make it easier to take things from Fedora/EPEL branches and convert them into CentOS branches, and that workflow would make the process of consuming EPEL packages (even with a rebuild) a lot less painful.
