Actually there's a similar mechanism in Python with the ctypes module:
https://docs.python.org/3/library/ctypes.html

I had used it a bit. For example in
https://trac.osgeo.org/gdal/browser/trunk/autotest/gcore/testnonboundtoswig.py#L166

Downside of this approach is that if you could get the function prototype wrong
and a runtime crash, as there's no checking against the .h files.
