Suggest better default project classifiers?

Migrating projects and calling them "alpha" is probably not the best idea.
The tool should either copy the existing classifiers or offer up better ones based on the user's judgment of the project stability:

classifiers = [ "Development Status :: 2 - Pre-Alpha", "Natural Language :: English", "Programming Language :: Python :: 3",]
