francewhoa updated that documentation page many times. He also made some changes described as Added "HTTP" to "General Requirements" section. Added "PECL uploadprogress bar appears, but it is not showing progress?" to "F.A.Q." section.
With that, I think that documentation page is updated. It just needs to be migrated.
I would not delete it, since the uploadprogress can still be used, and it works. What changed is that Drupal core does no longer require it, nor does it show a warning about a missing extension.
