Downplayed EMD further for certain queries.
And left EMD alone for other queries. (I just checked a couple of my bellwether keyphrases, and the EMD pages that have been at or near the top of the SERPs lately are untouched. One is off-topic, and the other is a thin page from a tiny personal site that clearly wouldn't rank at all without an exact-match domain.)
FWIW, our own site's overall traffic hasn't changed much over the last few days. Different sections or pages have had their minor ups and downs, but that isn't new.
(Our site is a long-established information site--all professionally-written and edited, no UGC. I don't think the forum rules will allow me to be any more specific than that.)
