What if Linux had a great asynchronous interface for reading files and FreeBSD had a terrible one ? Would NGINX team have bothered to implement this ?

Originally, as Igor has said in many talks, Nginx was written for FreeBSD, and supports what FreeBSD supports, and the Linux port has historically managed as it could. This is a case of actually adding something for Linux specifically, which is unuusual.

So the answer is it probably would have been implmented years ago if that was the case.

Originally. But the focus has shifted since then. There are a number of Linux-addicted developers in the team now.
