this changeset turns EA on. It was putback at hs17-b01, so it's never
been enabled in HS16 or before.
EA was on for all of HS17 testing, and we've been working on it, but
it's /just/ not quite production-ready, and the decision was made to not
spend the effort to try and fix it in HS17. We're hoping to get it fully
fixed in the current HS.
