Yes, but I will never have to use docker if I don't want to. For that matter, docker doesn't try to be cron, it doesn't want to handle mounting, didn't subsume udev, and doesn't encourage other project to link against it, and to drop all compatibility with non-linux systems. Systemd does, did, and is doing that right now.

"but I will never have to use docker if I don't want to."

I predict that fairly soon install instructions for a lot of different types of software will be "docker run ..."

For example, try running discourse without using docker.

Install deps, configure it, done. Looks straightforward, if a tad undocumented.

The thing is, the inside of a docker container is by definition indistinguishable from a regular linux install. Discourse isn't dependent on Docker, not the same way GNOME is dependent on systemd: It just encourages you to use it.

And others will list systemd as a hard dependency. The future will be "fun".
