I'd say again there are a collection of factors here, and then agree
with
you that those factors do weigh in favor of traditional deployment.

Yes, though that raises the question about the support lifecycle of
the dependencies.  If you're talking about shipping F21 FreeIPA
and rebasing the host to F22 (or equivalent for downstreams),
I would say that sort of thing is potentially a major win for
both the upstream and the downstream.

We could without changes in the upstream (Fedora in this case)
lifecycle allow running F21 containers on F22, as the component RPMs
are supported for N and N-1.

In practice with Fedora today though, the kernel for example is already
rebased
in lockstep between N and N-1 and has been for some time - encouraging
old apps on new host would just be a more flexible version of the
current
reality.
