NACK, this is explicitly the kind of thing we will never do.

Providing a long term stable API means keeping existing methods
operating unchanged, even if we have since introduced a new method
which can do the same thing in a better way. The cost of keeping
this existing code is negligible in context to the maint work of
libvirt in general.
