Alright, you're talking philosophy and me more about practical usage.
But why do you think apps own CSV any more in Files than in Finder? That's where a lot of my confusion stems.
Your view of x-callback seems off too, it's a way for apps to expose functionality in a generic way, so the opposite from being dependent on the relationship between any specific app vendors. Since there are many apps that let you glue together stuff yourself (and Apple provides one).

Anything on the local file system is obviously always available. For iCloud there's that status icon I referred to in my first post, but that's no different from desktop.

It's very practical. I know we're talking Apple now, but to give an example of a thing that happened to me last week: I couldn't send my wife a PDF with transaction details via e-mail "on the go", from my Android phone, because there was no chain of sharing that would link my bank's app and Fastmail. I could open (not save, just open) a PDF from the bank app, and I could share it, but under sharing there was nothing that would allow me to save it to the filesystem, and Fastmail app didn't show up on the list either. This could be fixed on either app's end, but a better fix would be for the OS to just provide the "Save to filesystem" share target for everything.

Likely - I had very limited experience with iOS (briefly worked with an iPhone that was recent some 3 years ago). It sounds like something similar to Android's intents system. If so, that's a bit better, but if Android's experience is to go by, a lot of linking you'd expect to work doesn't, either because of misconfiguration or purposeful prevention.

Sure, but there are voices calling for making cloud and local completely transparent; I'm strongly against that on the grounds I described.
Wow, peculiar. But ties into my point - there's now "Save to Files" _everywhere_ on iOS (even where it makes little sense) and yeah def a pain when apps that can clearly handle a filetype haven't registered as a target for it.
BUT prior workaround was as simple as a basic Workflow share action accepting any input then giving a list of options - Dropbox/Drive, push to desktop over SSH, try "open with" (? can't remember) which for some reason would have a slightly different list of targets...
So, file manager is good, obviously, but you weren't crippled before it.
