The idea is that stdlib modules that do not inherently rely on other C code (e.g. sqlite3 does not fall underneath this) would have a pure Python implementation with possible C enhancements. In the case of datetime that  code is done, so it won't go anywhere. In this case it would be bringing in a pure Python implementation like the one PyPy maintains. You can look at heapq if you want an existing example of what it looks like to maintain a pure Python and C version of a module.

So the proposal is to have something like we have for pickle, with
cPickle being the fast version and pickle.py the slow Python one ?

Since no CPython would use the Python version, who would be supporting
the Python-only version ?
