The are some genuine downsides in increasing the complexity of bootstrapping CPython when all you're starting with is a VCS clone and a C compiler, but those complications are ultimately no worse than those we already have with Argument Clinic, and hence amenable to the same solution: if we need to, we can check in the generated C files in order to make bootstrapping easier.

Are the generated C files perfectly identical? If you use Cython to compile the same file twice, will you always get a byte-for-byte identical file? If so, it should be safe to check them in, and then have a "make regenerate" that wipes out all Cython-generated files and rebuilds them. That followed by "git status" would immediately tell you if something failed to get checked in.
