Given that logic, Fedora should stop everything but Atomic.  The Cloud
image should be Fedora optimized for the cloud instance experience, just
like Workstation is Fedora optimized for the desktop user experience. It
shouldn't be massively different for Cloud than Server, b/c the use case
between Server and Cloud isn't that large.

Fedora should have a "typical" answer for what use cases are better than
XYZ distro, that isn't dependent on a (frankly) edge use case like a
container specific platform.  Atomic is a new and interesting thing, with a
very small and specific purpose and design.  That's a good thing and
shouldn't be used as an argument against the Cloud image.  Or even as a

I'm not a fan of this argument for minimizing the Cloud experience as the
real cost of "magnetic" storage in most cloud providers is small.  If
pulling Python saves 1GB of on disk installed OS space, then users in a AWS
environment save $0.24 a month / server in the most expensive storage in
the most expensive region (Sao Paolo if you're curious).  And I'm sure we
aren't shaving that much off the image.  I have to think the level of
engineering required to majorly redesign things around minimization efforts
are likely mis-placed if end user cost is the main metric.

That's where the Stack&Env WG work is important for us, as it could become

This ^^^  I'm a firm believer that the SCL work that got dropped is a huge
value when we want to talk about differentiating Fedora as a Cloud or
Server platform.  The ability to cleanly separate system requirements from
end-user platforms is huge.  I think the Cloud SIG should be jumping up and
down on getting SCLs back on track.
