"checkbox-style" Org todo keyword is possibly illegal

[meedstrom]

I confirm that...

• I searched the FAQ, issue tracker, discussions board, documentation, and wiki, and found nothing about my issue.

• I read the debugging guide and researched the issue to the best of my ability.

• My issue can be observed on the latest available commit of Doom.

• My issue can be observed on a stable release of Emacs (i.e. doesn't end in .50, .60, or .9*)

Describe your issue

I suppose that this hasn't broken anything important since its implementation ~8 years ago (doomemacs/doomemacs@03591ce77), given the lack of issues about it.

...but I want to raise the question. How would you express the "[ ]" keyword (a member of Doom's org-todo-keywords) on a #+todo: line?

If you type this in an Org file

#+todo: TODO PROJ LOOP STRT [ ] [X] [-] [?] | DONE

then you can see in the resulting buffer-local value of org-todo-regexp that Org takes [ and ] as two separate keywords, not the string [ ] as one keyword.

Reason I'm raising it now was that I wrote code that assumes that org-todo-keywords can't express anything more than what can be expressed on a #+todo: line (meedstrom/org-mem#18), so this led to mild breakage for at least one Doom user. I'll do a workaround, naturally, but maybe Doom wants to reconsider having this keyword at all?

Or maybe upstream Org should even throw an error on seeing spaces in a keyword? Don't worry, I won't tilt at that windmill. Perhaps on the contrary, it should allow [ ], < >, { } etc as a special case...

Also if it is already possible to express on a #+todo: line, please let me know!

I am that user 😊

Workaround done meedstrom/org-mem@3a1cde4

Closing because it's inconsequential. The [ ] keyword is still a hack, but hacks make the world go 'round.
