-// one-time profile reset prompt, and which then serves as a reminder that we
-// should not show the prompt again.
-//
-// In an ideal world, a single implementation would suffice, however, we expect
-// that third party software might accidentally interfere with some of these
-// methods. We need this redundancy because we want to make absolutely sure that
-// we do not annoy the user with the prompt multiple times.
