Shouldn't use of extern in documentation be removed?

[finlaydotb]

The getting started guide of hyber uses extern crate hyper https://hyper.rs/guides/client/basic/

I was the opinion that extern is no longer necessary and the new/current module system does not require.

and indeed, I confirmed this by removing the extern and the code snippet in the example still works...

Question now is, shouldn't extern be removed from the documentation?

Yea it could be removed. 🤷‍♂️

Think the extern stuff is for rustdoc testing, eg: rustdoc --edition 2018 --test _stable/server/hello-word.md -L "stable/target/debug/deps".
