Cast datetime from JSON string?

This is the behavior of the built-in DatetimeCast. It's not particularly critical for me, I added a new ExtDatetimeCast
Perhaps it is worth adding a special exception for dates in the Entity? toArray() executes castAs() and therefore the JSON gets not a string, but an object

PHP Code:

    /**
    * Support for json_encode()
    *
    * @return array
    */
    #[ReturnTypeWillChange]
    public function jsonSerialize()
    {
        return $this->toArray();
    }
