I agree with the points in your mail, but I wanted to expand slightly on
where I think Debian stands in the scale you described.

As DSA, I'd love to have Kubernetes or similar in stable so we could
have deployment using containers and just rebuild those and then service
owners could have a good way to do both development, testing and
deployment of their services.  It would also offer a much better way for
people to help out with services: If you want to help with, say,
packages.d.o, you can download the git repo and some sample data (or
database schema + importer), build a container with your changes and
then test them.

This is significantly easier than the current way, which is something
like: install a set of packages (defined in the debian metapackages
repo), then maybe set up some scaffolding (defined in dsa-puppet), then
deploy the service (with scripts that make assumptions about the
environment, host names, etc; if you're unlucky that «script» is only in
the service owner's .$SHELL_history file), then test that and finally
provide a patch with just the relevant changes for the feature or bug
you're trying to implement or fix.

So while we're not likely to have many deployments of each service,
lowering the bar for setting up services, defining a very clear boundary
between the service and its surroundings and making service development
much easier would be worth it for us.

This is a good point.
