I really don't see how the "...marketed toward children..." claim can even be made in the case of vaping products, regardless of the packaging, when these products are not typically even in view of the age group. I haven't owned a tv in well over a decade so I have no first-hand knowledge but I can't imagine there are too many e-liquid commercials currently running, and I'd bet there are none being run during the 'cartoon hour'. Apparently the BT brands are on the airwaves but that issue really has to be considered separately in light of the fact that BT is partly behind the push for regulation in the first place. 
Kid-friendly packaging won't work unless kids actually see it. Tobacco marketing was restricted because the packaging is/was prominently displayed behind the counter of every convenience store in the country. This is currently not the case with vaping products.
The idea of restricting packaging simply to appease the powers that be? That strategy is the first step off the cliff to surrender IMO.
