It's not perfect though. For example, right now Cosmopolitan won't do the really dirty hacks that Cygwin does to fully simulate POSIX like creating a virtual filesystem or spawning daemons and threads for handling signals. Cosmopolitan does however give you 90% the value at 10% the price. This has been great for my use case, since I'm mostly only concerned with greenfield development. I wanted the feel of POSIX but I didn't need to check off a box with a regulatory body that it conforms perfectly to POSIX. I'm also not trying to create a distro that leverages all the open source works written to date; Cygwin and MinGW are already doing a great job at that and I view Cosmopolitan as complementary.
