This bug seems to cry out for an add-on.  Then people who (think they)
know what they are doing can have the additional convenience, and the
rest can do whatever it is they do now.  I would guess there is
resistance to putting this into the base product on the theory that
99.9% of users will just hit "yes", meaning "get rid of this
unintelligible dialog and let me read the message", which is arguably
a Bad Thing.

Since we're getting offtopic anyway, I'll continue and opine that this
add-on would only be doing for self-signed cert.s and other unknown
CAs the same thing that the user *should* have done with those
commercial root cert.s: evaluate and install them individually.  (Of
course hardly any of us have done this.)
