There’s an API for that. e.g. KDE Spectacle uses it, which is why it can be used as screenshot tool under wayland no matter your DE. But by making it an explicit API, you can also apply an include/exclude list to the programs allowed to call this API, and e.g. exclude sandboxed applications from taking screenshots. Or e.g. add a permissions prompt (as on android or iOS) for an application to request to be on that include list.
