This is not currently planned. One interesting starting point could be to identify the Wikidata properties that express "same as". For example, many properties link to other data collections by giving IDs (which often correspond to URIs, only that URL datavalues are not quite implemented yet). However, the granularity of other databases is often not the same, and it might not be true that these IDs unambiguously define the identity of the subject. For example, we had on this list a question recently whether Norman Cook should have individual entities for his various synonyms or not; MusicBrainz has several IDs for him based on synonyms, but Wikipedia has only one article about the person. In such cases, links to other datasets should probably not be interpreted as sameAs.
Agreed. Naively, one might suggest to use something "weaker" like an inverted "alsoRefersTo".
So as to deal with synonymes, one could as well distinguish between name and entity/item/person/... in a manner like: "Satchmo" 'A name of the person Louis Armstrong' "Louis Armstrong" 'A name of the person Louis Armstrong'
We currently use schema.org's "about" for linking Wikipedia pages to Wikidata ids. It seems wrong to say that an abstract URI (about a Wikidata entity) is "the same" as the URL of a Webpage that covers that topic.
Agreed. Also, btw. Wikipedia links are not stable over time, neither in terms of URLs nor in terms of page contents. It is not uncommon for example that an Article about a "new" scientific concept published in the recent 60 years is turned into a section link into the article about its initial publisher. This certainly does not make the concept another name for the person :-)
