Just to be clear, attributes are designed in such a way that you, and third-party packages, can add this attribute *right now*, in your PHP 7.4 code, with no ill effects. In older versions, it's a comment (as long as it's on its own line); and in 8.0 and 8.1 it will be parsed as an attribute, but simply do nothing. You can add the attribute to every single class, and slowly remove it when you're confident of each class not needing it; or you can collect the E_DEPRECATED messages and add the attribute to every class mentioned. Even in PHP 9.0, there will be no subtle behaviour differences; the code will either run, or you will get an error in exactly the same circumstances as the E_DEPRECATED messages.
