I think macOS 27 has already shipped a version of this. I remember seeing a prompt for Firefox requesting access to Google Chrome data (presumably to import bookmarks/history?) recently.
If that's the direction things are moving in, I welcome the change. Fine-grained folder access controls (rather than only full iOS-like sandboxing or full disk access) make me much less hesitant to try new apps or have agents access more parts of my system.
But they really need to solve the issue of low-level utilities triggering dozens of permission prompts when walking $HOME. Having to approve or decline Documents, Downloads, Google Drive etc. directory access, all separately, is extremely annoying.
