please stop to prove even more that you have no clue of security
a firewall and security layers are to prevent from *UNKNOWN* mistakes in the future
they are to prevent expose network services to the WAN which most likely are
intented for the local netwotk by the user (SMB and so on)
hope that the ISP is blocking incoming SMB connections from the WAN is not enough
* file bugs don't help in that context
* the damned ISO image don't get fixed
* even if it is replaced it takes way too long
* the already existing setups are insecure
"If you really know what you are doing you do *not* enable network
facing services without installing updates first" was honestly
enough to prove your missing understanding of the ordinary user
because the ordinary users install his OS and starts whatever
he wants to do with his computer - thinking that the first he
does before start network aware services is too seek for
security updates is laughable to say it in nice words

there is nothing to read above
you don't understand what a "safe default" means
you even refuse try to understand it which is horrible in 2014

not for people care about default security

until you come up with better ones they are
disable the firewall is no solution

which make sense
your "if you are know what you are doing you don't" does not make sense
the user knowing whate he is doing don't need hand holding in any case
we are talking about terrible defaults

most of the time talking to people with a clue what they are talking about
is annoying - well, there are two choices. try to understand what they
are talking about or keep annoyed

well, maybe Avahi is a bad example because the major mistake in that
case already happened, but that's a weak excuse to make more wrong
decisions and throw the whole security of the distribution in a
default setup away
