I did. Chesterton Fence. fork() has been in Unix from the beginning. Taking it out at this point will cause more problems than it solves. Until you have a working Unix distro (kernel AND common userland services) that elegantly covers all of the forkless cases, your paper and their paper are just opinions. Theirs is a formally written one. Yours is a clickbaity one. And casting vfork() as any kind of improvement here is just bonkers.

And the rant is totally related: i.e. devs breaking things that worked just fine to begin with for the sake of doctrinal purity. It is usually a false doctrine.
