Cosmopolitan would actually be a great fit for Python extensions, since manylinux1 requires RHEL5 support and Cosmopolitan is probably the only modern C library that still supports it (glibc these days needs rhel8+). Maybe someone will figure out a way to compile a single-file library that's simultaneously a .dylib / .dll / .so just like how Actually Portable Executable does for programs.
