As a third party to this debacle, all I have to go on is the comments people have made, but a few of them have asserted that that language was added later on and some initial versions of this change either outright lacked that warning, or else used styling tricks to make it difficult to notice. I lack the time and/or motivation to go digging through the commit history for that plugin, but maybe someone more enterprising could do so and verify if that warning was always present and presented in such a visible fashion.
