If you have the URL of the folder, but don't know what's inside the folder, a browser won't generally display any of the content unless it finds an index.html file (or something like an .htaccess file, if the server supports it). But if we have nav.html and rename it to index.html, then any browser will open index.html when you go to the folder URL. It's just a convention that makes it easy to find this critical document.

Also, manifests are often handled by dedicated javascript routines; a manifest in JSON is quicker and easier to digest than, say, if all information is encoded into RDFa as part of the index file.

Doh. I meant "this should not be exclusive" :-(
