The second part of their mission statement, "to restore those names to their families..." would require producing family trees. So it sounds like their goal does encompass genealogy. But perhaps their net is so wide that, as you say, it is not reasonable to genealogy a "focus." It would be awesome if they could be persuaded to make Wikitree the primary hub for the genealogical portion of the project, but I see links to FamilySearch already on the site.
