Not at all. The Trove classifiers *always* mean what the package author
wants them to mean. In the specific case of Python :: 3, they should
mean what makes most sense. For an application, it might make most sense
to specify the language it is written in. For a Python library, it
surely would make most sense to specify the Python version it supports -
notice, however, that this is *also* the Python version the library is
written in.
