Comment (by afercia):

 Quick screenshot (see below), to remind that plugins can add their menus
 also on the right of the sidebar. Tested with the "View Admin As" plugin,
 and I guess there are other plugins that do the same.

 Placing the "Recovery Mode Exit" on the right on small screens would
 likely break the admin bar layout.

 WordPress never established strict rules for what plugins can add in the
 admin menus so basically there's nothing to prevent plugins to do what
 they want other than a few CSS rules that are very easy to override. The
 related hooks can't be disabled because they're used by WordPress itself.
 Relying on CSS doesn't seem a good idea as well.

 I'd tend to think we should explore a new, reliable, way to conditionally
 render menus in the admin bar.

 Not sure if it's possible (just brainstorming and would appreciate any
 feedback), what about to:
 - introduce a new hook(s) exclusively meant to print out the Exit Recovery
 Mode link and the other WordPress menus that should be available in
 Recovery Mode
 - when in Recovery Mode, disable all the hooks like `admin_bar_menu`
