Well, yes, but if you look at the OS section of the Trove list
you also find different implementations of BSD under the
BSD category:

Operating System :: POSIX :: BSD
Operating System :: POSIX :: BSD :: BSD/OS
Operating System :: POSIX :: BSD :: FreeBSD
Operating System :: POSIX :: BSD :: NetBSD
Operating System :: POSIX :: BSD :: OpenBSD

(just to take one exmaple)

See http://pypi.python.org/pypi?%3Aaction=list_classifiers for the full
list.

Also note that Cython is listed as:

Programming Language :: Cython

even Zope is listed as programming language:

Programming Language :: Zope

so there isn't all that much consistency in the naming.

BTW: Stackless is missing from your list.
