Additionally, I'm not certain of the use case cited. Isn't the utility of a site like http://python3wos.appspot.com/ in seeing which popular or widely depended upon packages have no python3 version? With that in mind, the listing on that page wouldn't seem to depend on whether a package's author intends to port to python3. It depends more on whether the package has some well-known python3 counterpart that dependent code can be (easily?) ported to use instead. I'm thinking here of things like: try: from simplejson import loads except ImportError: from json import loads Seems kind of a miscategorizaion to use the Programming Language :: classifier for that.... Some sort of classifier that indicates that the software is only relevant for a certain version of python seems better. Looking at the existing catgories, maybe something like Environment :: Python :: 2 would be appropriate. (Although, ugh,I think that someone jumped the gun and added Programming Language :: Python :: 2 :: Only without waiting for the results of this discussion to finish. Not sure if that can be reverted or if it's already too late.) -Toshio
