This property was added together with `noopener` to protect users with older web browsers that do not yet support `noopener`. The latter now is well-supported since several years and in fact even is the default value in modern web browsers. This allows us to drop the `noreferrer` from those links safely. Stripping the `referer` header can be more reliably achieved with the `referrer-policy` header that also gives the administrator more fine-grained control.
