I have to disagree on that point, integration with underlying OS and low-level
services is important. If that integration doesn't exists, it's
off-loaded to the
operators. So downstream packages bring more value than pip deployment,
as it will pull dependencies (not just things from PyPI), working combination
with underlying OS components etc.

Packages could be used in a variety of different configurations, even ones we
didn't expect. Any sensitive scenario that we can't support is likely
to be a packaging
bug for me.

In some cases, it makes sense for fine-tuning, but generally, you just want to
get things work and tweak your configuration.

+1
As a matter of fact, I prefer that packages to be as agnostic as
possible about the
deployment and let that work to the orchestration tool.
