Because it does not use inheritance. It is not going to create
properties on subclasses without
you noticing it. Also, metaclasses are brittle: try to use them with
__slots__, or with non-standard
classes (i.e. extensions classes), or try to use multiple metaclasses.
I wrote a paper
about metaclasses abuses which should be published soon or later; you
can see the draft
