I assumed this was previously implemented in the initial Penguin release, as part of "over optimization" adjustments - that's when i saw a big fall. Some of the dumbing down might have been reversed for quality sites.
Matt does state " low quality" domains - so I'm actually reviewing some sites that appear to have improved. Maybe this adjustment had some positive and negative effects to apply.
As usual I'm not seeing any effect on brand sites with exact match domains. Does anyone support or reject these observations?
