The expected Belarusian challenge became a mere matter of sorting out the minor medals - perennial rival Nadzeya Ostapchuk got the bronze after managing 19.86m, while Natallia Mikhnevich took silver with 20.28m.
Adams, then known by her married name of Vili, posted a string of 20.56m, 20.40m, 20.26m, 20.01m and 20.52m. Complete and utter dominance.
"You've put in the hours, lifted the weights, thrown the shots, done the drills and it's just getting out there and doing it," Vili said in the aftermath.
The four years since have been turbulent. Adams went back to her maiden name after separating from her husband, Bertrand.
Another divorce of sorts proved more shocking as she dispensed with coach Kirsten Hellier after 11 successful years together.
Her partnership with French throwing guru Didier Poppe was ill-fated and, after a difficult 2010, she ended that formal arrangement, too.
But under the guidance of Switzerland's Jean-Pierre Egger, she has returned to her crushing best and is expected to win in London.
It would seem all she really needs to do now to defend her title is to smack the crap out of it.
