I have no opinion on the merit being discussed except this part, 
because I do think that keep adding more attributes will hurt D 
in a long term, in fact this is becoming a pattern in this 
language... there is a problem? -Let's add this attribute to 
solve.

If possible this should be thought in a way to be solved without 
adding new attributes.
