Previously, I had changed the default value to "", to force users to set the SECRET_KEY value (the app refuses to start if SECRET_KEY is empty). The problem with that is, out of the box, with the default configuration, the tests also don't run and complain about the empty SECRET_KEY. So, a compromise: revert back to the default value "---". At runtime, if SECRET_KEY has the default value, show a warning at the top of every page.
