Exactly the same reasoning can be applied to hostname and ident - nothing is 
changed in this regard by adding one more parameter. So if there's a chance of 
leaking src_addr than we're also leaking hostname and ident as well. Do you 
have some actionable suggestion?

1 - yes, 127.0.0.1/8 is an IPv4 address?
2 - sorry, I'm completely at loss as to what's your actual point

I'm adding new parameter to logging config and I'm illustrating its use in a 
config file in the same commit. Do you have some concrete suggestion on what 
should be done differently?
