I'd forgotten that you can just enable minor modes without any of that.
You can just say

((org-mode . ((mode . org-startup-folded-mode))))

Or of there are different types:

((org-mode . ((org-startup-type . foo)
              (mode . org-startup-folded-mode))))

There's dozens of variables that have to be set before `org-mode' is
called?  That sounds like an fragile design.
