The code itself is mostly solid. The only issue I see is a question I
have about if we really need to be defining so many of the
"EFX_POPULATE_..." macros in patch 1 as it seems a bit gratuitous and
could likely be replaced by just adding multiple dummy fields to a
single macro instead of defining multiple macros to get to the end
goal.
