You say "usually," but I see "occasionally." As an example, here's the LC authority record for me: http://id.loc.gov/authorities/names/n89613425.marcxml.xml, and if you can find "other important contextual information" you are a better reader than I am. Plus, when that information is available it's in a note field and can be quite cryptic:

"found: Phone call to Curbstone Press, 07-13-94 (Michael H. Cooper is a pseudonym of Michael Clark; b. 6-11-51; res. in Alaska)"
"found: Message from J. Baker, 11/08/88 (Michael D. Cooper; b. 10/30/41) "

Thomas, I think you are being overly optimistic about the state of authority data today. I agree that it can get better, but I don't agree that VIAF extracts much "data" -- it basically gets what you can get from a MARC name heading field, and adds in titles of works (which it gets from the WorldCat database). There may be more information in non-US authority files, but rather than relying on impressions it would be better to have a good study of available data.
