It's not a matter of convention. They mean different things, so you use
each depending on what you mean.

Right. So you use ‘Abc.message’ when you specifically want a class
independent of any instance, and you use ‘self.message’ when you want
the attribute of this instance (with fallback to the usual resolution
order).
