It's possible to use docker as a package manager. I worked jobs where did exactly that, because we needed to compile certain dependencies for our application, and it streamlined the whole process.

There's zero reason you couldn't create a small abstraction layer around docker so you can install "executables" that are really just launching within a container. I mean, isn't that the whole idea behind flatpak, snaps, and appimages?

The point is to leverage modern abstraction techniques so that people don't need to learn a new system.
