> Yeah I also concern about this. There ARE some case if a network
environment only have "lo", but it use some other way to built a proxy with
only "lo" interface.

For example,
Android phone, setup a proxy on the phone and redirect by adb (I know this
is a VERY rare case... but I have use it several times, don't argue why I
use this werid setup.. this is only for an example).

So warn user about no network is good, but in some case it's still useful
make user can force the connection. Even proxy is not supported right now..
