Link-local (IPv4) as a connected state?

["W. Martin Borgert" <debacle debian org>]

Hi,

in case of a machine that is only connected via a link-local IP
address (169.254/16), the machine is (normally) not "fully"
connected to the internet nor the LAN. A well-known OS from
Redmond warns the user in this case about the probably lack of
connectivity, I learned today. NM seems to be happy with the
link-local connection. Would it make sense for NM to distinguish
here as well? This would make it easier for programs using the
NM API to "know" (guess), whether the machine is really
connected to a network or not. Or should this better be done in
the application instead of NM?

Thanks in advance!
