At the minimum it changes the way parentheses indent automatically when
editing source code blocks. Below is a minimal demo, documented using
our favorite system.

All the best, and stay safe.

* Demo of the effect of disabling elint
  1. Save this org into file =org-elint-disable.org=
  2. Save the following elisp into =minimal-org.el=, replacing the
     location of org mode with your path:
     #+begin_src elisp
       (add-to-list 'load-path (expand-file-name "~/src/org-mode/lisp"))
       (add-to-list 'load-path (expand-file-name "~/src/org-mode/contrib/lisp" t))
       (add-hook 'org-mode-hook (lambda () (electric-indent-mode -1)))
     #+end_src
  3. Toggle the last line
     #+begin_src elisp
     (add-hook 'org-mode-hook (lambda () (electric-indent-mode -1)))
     #+end_src
     in =minimal-org.el= to see the following effect:
     1. Open this file with
        #+begin_src sh
	  emacs -Q -l minimal-org.el org-elint-disable.org
        #+end_src
     2. Type C-c ' for (org-edit-special) in the source code block below,
	and follow the instructions on the comment line.
	#+begin_src java :exports none :classname Demo
	  class Demo
	  {
	      // 1st press RET at the end of this line, then type TAB and }
	#+end_src
