I myself don't do that and instead I treat C constructors as a
convenience for C programmers because if you use them instead of
GObject.__init__, the subclasses will have the same GType as their
parents and things like signals and properties will break.

I would do instead:
class MyBox(clutter.Box):
def __init__(self, **kwargs):
GObject.__init__(kwargs)
Or just don't override __init__ at all if you don't need it.
