I already have access to the beta cluster as @Lucas_Werkmeister_WMDE (see T188427), but I also use it as a volunteer (and am sysop on Beta Commons), and it would be useful if I could work on it using my volunteer account, so I can avoid mixing WMDE and non-WMDE activity. (For instance, I’d like to try using maintenance/undelete.php to resolve T293558.)
