But I think this filter has changed without changing the label, because it shows me sites with PHP 7.4 (and probably lower). In the file mainwp/class/class-mainwp-manage-sites-list-table.php I see the status is still called phpver7, while it tests for 8.0.
Besides this bug it would be nice if we can adjust this filter to <8.1 or <8.2 etc.
