I don't think "struct file" has any meaning to any userspace developers, and as such doesn't belong in documentation for userspace programming. It's an implementation detail of the kernel that userspace developers have no need to be aware of. There's already enough leakage of broken kernel internals (e.g. tid vs pid vs tgid) into userspace documentation that's immensely confusing for new developers without adding more of it.
