I've given it considerable thought, and my criminal mind hasn't been able to dream up a single situation in which a CAPTCHA pane would stymie any individual, other, perhaps, than an imbecile, who knows or can guess my admin password.
I'm curious to hear what scenario yours thinks would benefit from one.
I wasn't thinking so much of the CAPTCHA pane than of the admin authentication it was associated with. I suspect the CAPTCHA module was included 'by default', and for the same reason it's included elsewhere despite its limited utility. I do agree with you regarding other questions you can ask about the rationale behind certain aspects of Rapport's functionality and its UI.
