Is that a solution we want to support OCP customers on?

I don't see why not. As we go down the path of reducing the size of atomic host, we'll need to install dependencies that may not make sense to deploy containerized (storage dependencies for example), so package layering seems like the proper place to manage those dependencies. I would view the tuned profiles in the same way.
