They did... But you was on point not now most people are just sticking to co2 or Rosin
The problem with room temperature ethanol extractions is they extract a lot of chlorophyll but I guess if you do it in Sub-Zero temps it doesn't do that
It does plus super dangerous co2 knocks the trichromes right off keeping the chlorophyll in the plant. . But a good flushing before the plant is done will help get ride of all chlorophyll
