I agree on not describe the constructor signature. But I can't 
agree on the reason why.

If you have to use an existing framework with defined interfaces
the missing constructor signature doesn't make sence if the
framework at the same time offers implementations which use
a specific signature. It's just a leak of information.

I'm also against describing the __init__ signature in an 
interfaces but there is another reason. 

The missing __init__ signature in the interfaces make only 
sense if it comes to reduce the variants of it. It whould 
not be helpful to have several different named interfaces 
just because they support another constructor signature.

But describing a constructor signature is not in general a 
bad thing.
