This seems like a behavior change in upstream GRUB, and due to us having
shipped it with upstream behavior for years now, I am not sure if still
want to go back to the 2014 status quo now that people have been exposed
to the new behavior for 10 years.

** Changed in: grub2 (Ubuntu)

Title:
  GRUB2 asks for password when booting

Status in grub2 package in Ubuntu:
  Won't Fix

Bug description:
  Following this guide:
  https://help.ubuntu.com/community/Grub2/Passwords you can set a
  superuser to prevent anyone from editing grub lines, but allowing them
  to boot anyway. Back in Ubuntu 12.04, you just edit
  /etc/grub/40_custom with:

  set superusers="John"
  password John foo
  export superusers

  then you execute sudo update-grub2 and that's it. You can't edit grub
  entries without the password but you can boot.

  Now in Ubuntu 14.04, GRUB will ask for the password even when you just
  want to boot.

  A workaround is editing /etc/grub.d/10_linux with:

  CLASS="--class gnu-linux --class gnu --class os --unrestricted"

  The "--unsrestricted" option does the trick. But the "way to go"
  should be adding a line in /etc/default/grub so the grub-mkconfig will
  auto-edit the 10_linux file.
