I went ahead and cooked up a proof-of-concept patch, which

(1) adds safe-local-variable properties to org-todo-keywords and
    org-todo-keyword-faces,

(2) stops applying default-value to org-todo-keywords,

(3) delays regexps/font-lock setups until after file- and dir-local
    variables have been set.

While this patch contains a few things that make me weary[1], it solves
my use-case, and passes the current test suite with Emacs 26.3 and 28.

Does this look sound overall?  Does anyone have any idea what kind of
breakage might be slipping through the test suite?

Thank you for your time.


[1] - It's hard to feel confident that moving org-regexps-and-options
      and org-set-font-lock-defaults like this will not introduce
      regressions.

    - Also, these safe-local-variable validation functions could
      probably use some unit tests.
