Hi,
Thanks, we are aware of this. As those warning don’t really have any side effects and don’t appear unless the extra warnings are enabled, we recommend simply suppressing them via per-file settings.
If you don’t want to do that, you can send us the patch adding the necessary attributes and we will include it in our release branch, but we don’t have any plans of addressing them on our side, as we prioritize other features over it. Sorry.
