We have already put on our plate to do a proper review of it:

This might need to be discussed some more, but probably what needs to be
done is filtering RFC1918 by default. But Tails is also meant to be able
to produce documents. Some users might need to get sources on a NAS or
use a printer in their local network.

So implementation is not only about about changing three lines in the
firewall, but also about having a way for users to allow access to the
local network is also needed. This is not hard, but makes it less
trivial.
