Never do by choice, distribution repos are good enough for me.
The bigger problem is when projects only officially ship as docker images for some banal reason.
Then don't use those projects, or build them yourself, or use non-Docker options. I'm aghast that people think they need an expensive, bloated container runtime to run software. It's never been necessary.

As opposed to what? SystemD?
I think what he's probably thinking of is more like using a virtualenv for python. Or bundler for ruby.
Yeah and installing it as a systemd service, which uses basically as much namespacing/cgroup/supervision/mounts as any other container runtime.
