Is it time to remove python-numpy from testing?

[peter green <plugwash@p10link.net>]

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?

* Note: since buster the python-numpy source package only builds python 2 related binary packages,
the python3 numpy binary packages are now built from the numpy source package.
