Why does NM attempt to set a default route for a OpenVPN connection 
where the OpenVPN server does not advertise itself as a default route? 
It would almost never work, and sounds like a bug to me.

Anyway, with "Use this connection only for resources on its network" 
set:

# nmcli connection show $MY_VPN|grep never-default
ipv4.never-default:                     yes
ipv6.never-default:                     no


It no longer sets the connection as a default route.

Error: Object 'logging' is unknown, try 'nmcli help'.
# nmcli general logging level TRACE domains ALL:VPN_PLUGIN
Error: failed to set logging: Unknown log level 'VPN_PLUGIN'

So in the end I came up with this one:

# nmcli general logging level TRACE domains VPN

And it helped me debug this - thanks!
