It's incredible that wayland is so incapable that it can't even keep this kind of state, and we're back to having to basically having to write .xinit scripts. Because that's what little so far wayland offers: less than xinit.
Persistence of "mental state" mostly. By setting up a compose, you have a written down notion of things like volumes, environment variables and other elements stored somewhere for the behaviour of the container, that can not be ignored or defaulted if you don't wish it, for when you need to undo and redo a container and default behaviours are important.
While sure, those elements can be set in a loooong ${engine} run... command, it's easy to forget to set up something important or copy and paste an accidental endline. A compose file (plus a sample envfile, if you so wish) helps keep the way to set up variables and state under control. Made much easier now that we have both docker-compose run and podman-compose run.
Fam, the modern alternative to SSHFS is literally SSHFS.
All that said, if your use case is mostly downloading and uploading files but not moving them between remotes, then overlaying webdav on whatever you feel comfy on (and that's already what eg.: Nexctloud does, IIRC) should serve well.
Never said they conflict. Said they're not a "basic feature". Sigleplayer has lived without cloud saves since around 1960.
Heck, most modern consoles have a USB port, I'd consider "offline save" more "basic" than "cloud save". After all we all know by now the corporate internet can't be trusted.
Looking at the various recent mishaps, like this one, I'm two steps from offering my services as an instance admin. Or would be, if I wasn't already busy with a half-time job and the other half of the time wasn't trying to have a social life.
My kneejerk reaction coming from the '90s is that if I wanted the same branding for everything, I'd just use Apple or Gnome. At the same time, constructing brand image on top of a third-party base that is in development and can change over time can be difficult, or just "not worth the $RESOURCE". So I'm currently in the position that something like "universal Mastodon view with brand accents" would be the most fitting thing for the Fediverse.
The 2A is there for you to do things, but it's not only simply about rising up. It's about instrumentalization. When every citizen can be armed "just in case", all you need is for that to statistically compound into a Luigi or two getting three lucky marked shots on the tyrant du jour.
