I sat on the phraseology working group at SRG that decided this change. No civil ATC rep agreed with it and I suggested that we file a difference with ICAO for class G airspace below FL100, but the RAF rep (probably not a controller) said that they had no objections to full implementation, so that carried the argument. Notice how many military ATC units use the new phraseology? I don't think it's reached JSP 552 yet.
