Right, but that link won't change even if they switch to typescript, which is where my point lies. The benefit comes to package contributors, consumers looking for accurate documentation, and anyone that uses a build tool/IDE/or even a text editor with basic syntax highlighting. All of this while having no negative impact on people who only click your link. I'm not encouraging everyone to adopt it. I just struggle to see any objectionable aspect from anyone that is solely on the consumer side. Basically, if you aren't using any tooling, the world will keep on spinning.
