This would provide a strict equivalent of attrs behaviour. But for which usage ?

I would rather enable this only for classes that are read-only, so that the behaviour is intuitive.

As of now there is no concept in python for descriptors with only a __set__ method and no __get__. (we should maybe make a pep :) )

So we're left with putting that in the constructor... which is exactly what attrs does, and would break the "isolation" philosophy. So won't fix
