This is a FoafVocab issue, documented as such by linking it from the IssueTracker page.
2004-01-12 proposal by Julian Bond: foaf:preferredContact, to provide a public contact point where a person is happy to receive unsolicited messages from people who have found their FOAF. (email/phone/IM/etc) (rdfweb-dev mail)
When an issue is resolved or its status w.r.t. the FOAF spec changes, that changed state of affairs should be documented somewhere less transient than the wiki. See IssueTracker for more notes on issue management conventions.
