Ah right, we can't just match "org-*", indeed.

Maybe if we can identify a "first org-*.el file" (i.e. a file which
*any* use of some part of Org mode would necessarily load pretty early
on), then we can reduce this check to:

- check if that "first org-*.el file" is already loaded.
- if no, load it
- if yes, compare the output of `locate-file` to what is found in
  `load-history`, and in case it doesn't match (because of a new
  directory in `load-path`), signal an error (or maybe force a reload
  instead?).

We could even provide a new `require-with-shadow-check` function that
does just that.
