At least 80% of Docker's value to me is as a consistent-everywhere, very complete server daemon package manager. Serious packages for work? They're there, and up-to-date. Screwing-around stuff for home (Minecraft server, Jellyfin, et c.)? It's all there, same interface, just a couple minutes to add and configure another daemon at approximately its latest version, and I don't even have to think about which distro I'm running.
It's the container registry that I'd miss, not the actual container functionality, and that's what would have me reaching for Vagrant and distro packages again until something similarly good arose (or maybe there already is a viable replacement, which I'd find via search in short order if I actually needed it)
