Concretely, because for a long time we have used the uWSGI application server and it manages forking worker processes (among other things), and AFAIK nobody has yet proposed trying to replace that with something built around the multiprocessing module. I'm actually not aware of any popular Python WSGI application server built on top of the multiprocessing module (but some may exist).

What problem do you have in mind that the fork server would solve? How is it related to this issue? I looked at the docs and don't see that it does anything to help sharing Python objects' memory between forked processes without CoW.
