well, not in term of future extensibility. Having an empty constructor
and calling it in children classes allow me to change my mind latter,
and to add some initialisations in the __init__ method without having to
change all the children classes.

So ignore it. This warning has been added since our experience has shown
that developpers may abuse from this construction. That doesn't mean you
should not use it in your case.

this message indicates that the comma after "address" should be followed
by a space. The line number problem is a known bug, coming from the
compiler.ast module in the standard library (all nodes doesn't have a
line number, and so sometimes pylint fail to guess it).

it is working. It only tells you that class method should have "cls"
instead of "self" as first argument. I'll probably reformulate this
message the next pylint version to make it clearer.

I know. This is just a bonus. I think you're looking for the
--include-ids option.

Yep ;o)
