Don't know. Perhaps we could call it the FigLeaf pattern
(covering up what you don't want seen)?

There's another possibility that's even more pythonish
(I won't say pythonic, since it's not necessarily
a *recommended* thing to do):

class A:
   m1 = B.__dict__['m1']
   m2 = B.__dict__['m2']
   ...

I propose calling this the Magpie pattern (stealing
the shiny baubles you want and hiding them away in
your own nest).
