How about numarray?

$ rpm -q --requires python-numarray
/bin/sh
/usr/bin/env

I seem to recall several Python apps moving from numpy to numarray in
the past, so it should be doable. If we want to do this, we should
probably create a tracker bug in Bugzilla.

That sounds reasonable. Like "new activities using numpy will not be
accepted"? If the porting work from numpy to numarray is documented,
this should be linked to from the policy as well, so that people can
adapt their activities.

Probably a good thing to do, yes.
