But Urls are easy to mint and avoid centralization issues; they are the de facto identification scheme on the web.

OK, makes sense.
But then, the URL to a manifest may change, or two different URLs can point to the same manifest:

https://resilientwebdesign.com/manifest.json <https://resilientwebdesign.com/manifest.json>
https://resilientwebdesign.com/books/../manifest.json <https://resilientwebdesign.com/manifest.json>

(dumb case, but you see the point).

All I'm saying is I understand the manifest _can_ be used as an identifier in a given context (e.g. a UA), but there's nothing to say about that in the spec, right? There's a URL, people can use that as an identifier or not.

As far as I can tell, there's no such concept in web sites and apps, and I don't see that publications need anything other than a loosely specified "dc:identifier" property in metadata. (Maybe I'm wrong, I'm just not convinced yet :-)
