I have no prove/quote for this, but I can imagine that SE's want the
quickest possible way to create a running cluster. Taking into
consideration that one might re-deploy a system over and over again to
demo something.
Skipping the updates will save you some time I guess..

I actually think that splitting stage.0 in
  1) mandatory calls ( like ceph.sync ceph.packages.common .. )
  2) update/maintenance
  3) calls for a special env(actually _optional_)
could make sense here.

the split does not necessarily need to result in two new stages but
could also be managed via a ENV_VAR or something of that nature.
