I would be nice to be able to use something to "generate" C extensions, maybe even from pure Python code. But someone has to work on a full solution to implement that.
Perhaps a "argument clinic on steroids" would be the proper approach. So, extensions would mostly be written in C. However, we would have a pre-processor that does some "magic" to make using the Python API cleaner. Defining new types using static structures, for example, is not the way to build a good API. The other approach would be something like mypyc + cffi. I agree with others that Cython is not the right tool.
