yes I have patch to enable this via a mode switch (https://bugs.freepascal.org/view.php?id=36350) but it has been acknowledged and then ignored without explanation since 2019. This is still the only way we can use operator overloads for generic objects and objects are the only way to have record inheritance so it's a critical missing feature in my opinion.
