https://www.swift.org and https://swift.org are the same website. Can you clarify why you want to prefix it with www?

[spageektti]

We are removing www from links, not adding (#13633), so If www* redirects to the same site we should not add that.

My reasoning was that it's better to have the direct URL to documentation rather than a URL that redirects, as redirects may not be in place forever. I will leave it up to the maintainers though.

I agree with you for other redirects, but I can't agree that it matters for this kind of redirect.

Fair enough, closing this.
