python-numpy* is no longer buildable in testing due to the removal of the "cython" binary package.
The maintainer has requested removal of python-numpy from unstable but the ftpmasters have not yet
actioned it, presumably because there are still reverse-dependencies in unstable. A rc bug is
present but will not cause autoremoval because python-numpy is on the "key packages" list.
All of the reverse dependencies of python-numpy have already been removed from testing. So IMO
it makes sense to remove python-numpy from testing at this point, do other people agree?
if all reverse dependencies of python-numpy were already removed from testing and we are not going to reintroduce python-numpy into testing I think it's good idea to remove python-numpy from "key packages" list and thus allow autoremoval.
