There is some doubt about the drivers of Merc using das at Melbourne and possibly the next few races.While Bottas is enthusiastic (and swarmy for keeping it secret for a year) Ham is not entirely keen so it seems probably with the many other button/lever pushing and pulling to maintain a quick pace.Also though it may have been 'passed' by the federation there could still be reason for protest at the grey area about moving aero,particularly on the straights and the federation can change it's mind.
