No, because Emacs does not perform fallback. (GNUTLS automatically
upgrades away from SSL 3.0 if possible, and this upgrade is a
cryptographically protected part of the handshake.) Emacs could warn
if a connection uses SSL 3.0. However, it will be difficult to
explain the exact implication of the warning. At present, there is
not even consensus among programmers how bad SSL 3.0 actually is.
