Would it be so hard to say “when I press command-v, send a paste event to the focused window containing my clipboard contents”? Sure some programs would want to customize keybindings, so unrestricted access could be allowed on a per-app basis, but why should any app I install have access to all of my copy events ever? Similarly for private files: MacOS already alerts you when something tries to read from “~/Desktop” for the first time, why not allow users to extend that to “~/.ssh” and “~/.gpg” too?
