*SJ* - Rephrasing... reminds me of some of the discussion we had within Schema.org where I pushed for Quotation often. https://schema.org/Quotation where we didn't put much work into helping connect more dots, but still it's there.
Quotations often tie into facts, "he said/she said", dispute resolution, etc. And where it seems Wikidata's *quotation* https://www.wikidata.org/wiki/Property:P1683 property might also somehow play a part in your proposal.
*Adam* - I think it would be nice to have a concrete example of some clusters where a quotation is part of the fact basis.
