Native languages for web development

Why are "native" languages* almost never used for web development? Shouldn't FastCGI be just as good as what web servers do with Perl or PHP? What am I missing?

* languages designed for AOT compilation to opcodes like C++, Ada, C, D, Pascal, or Go

Go is often used (at least relative to the number of Go programmers) and it's a great choice for web backends, since it's fast, supports concurrency and parallelism, has great web server related routines in the stdlib, is type-safe and memory-safe, many errors are caught at compile time (not on runtime, like the interpreted languages), etc.
