The name “Share” is probably just a holdover from older iOS versions when it actually was purely a share feature. It ought to be renamed to something else now, like “Actions” or something to reflect the fact that that one button is how you: open the file in a specific app, run automations on it, share it with friends, save or bookmark the thing, etc.
