That would be weird in classes that override the constructor (__new__), which is what is actually called (not __init__, except contingent on the result of the constructor) when the class is used as a callable.

Not to mention the need to define methods in the class body, and be able to distinguish them from local functions in the constructor/initializer, which is a pretty good argument against the class body being the constructor or initializer.
