. As the manifest is the only resource specific to a WP, its address is a logical choice.

I didn't want to raise this uniqueness issue before we agree first on an answer to your question but uniqueness is not really required neither imo.  An unambiguous identifier (meaning that two different WP can't have the same I'd) is sufficient. This idea was discussed in the NewsML G2 WG some years ago, I may find some traces of that. 
Or we can define this id as a "canonical" URL (I Imagine there is such a thing in the W3c toolkit)

It was my first view on this. A metadata simply defined as an unambiguous Id. But giving a bit more precise indications may help adoption and avoid ambiguities.
