make DEVELOPER=YesPlease would die due to

advice.c: In function 'vadvise':
advice.c:123:17: error: enumeration value 'CONFIG_SCOPE_WORKTREE' not handled in switch [-Werror=switch]
  123 |                 switch (setting->scope_hint) {
      |                 ^~~~~~
advice.c:123:17: error: enumeration value 'CONFIG_SCOPE_COMMAND' not handled in switch [-Werror=switch]
advice.c:123:17: error: enumeration value 'CONFIG_SCOPE_SUBMODULE' not handled in switch [-Werror=switch]

We probably should have

		default:
			BUG("advice settings at wrong config scope");

or something there.
