See https://wiki.php.net/rfc/override_properties. Specifically, if we had already added #[\DelayedTargetValidation] as part of 8.4, and that other RFC passes, there would have been a place to use it - on class properties in code that supports 8.4 and 8.5 but wants to indicate that the property overrides a parent property. Fundamentally, #[\DelayedTargetValidation] needs to be introduced *before* it is useful, because it is designed for supporting attributes that change in future versions of PHP. Introducing it in 8.5 might not help for #[\Override] on property, but it would help for any attribute changes in 8.6+, e.g. if #[\Override] starts to support class constants. -Daniel
