anything that doesn't have (preferably zsh) shell completions. I mostly discover flags with tab completions and the attached help to it (maybe that's only a zsh feature not sure if other shell have help on flags on completion) bonus point to very smart completion, i.e: on kubectl if i do kubectl -n foo get pods [TAB] it will get the tab from the namespace foo on completion not from the default/current namespace.
