Ideally it would keep using both as long as there were some
"important" connections persisting on the old one, and there would be
a socket option for applications using unimportant persistent
connections to flag them unimportant.

Maybe once everyone finishes switching to https...then the hijacking
will cease to work, and to give a reasonable user experience, they'll
have to drop hijacking.

The assumption is that the system software, possibly interacting with
the user if the user were allowed to change network settings, would
handle the status of the real connection, and expose it only though
the virtual interface through the user when it's actually working. For
semi-advanced users, this could allow transparent migration (even
keeping your ssh/chat/etc. sessions) if you integrate it with vpn.
