Agreed; although the workout messed with my technique, I don't think I came close to injury at all, which I sometimes did when I worse at oly lifting.
The second point is definitely valid, too; if one of the main things you're training for is metcon ability and you don't do the full lifts very seriously, power oly variations for reps are another perfectly good way to train metcon.
