Honestly, with how good skin skis are now it might be worth exploring getting rid of grip waxing altogether. I realize this may sound like blasphemy but it's worth brainstorming 'outside the box' solutions IMHO; moving forward I believe simplifying and reducing the costs/complications/variability of waxing would be a goal that could pay great dividends.
Changes in culture/tradition are always hard but it seems clear to me at least that the amount of money spent on the esoterica of ski waxing is going to be increasingly difficult to sustain. Skins (or zeroes in the right conditions) may not be as good as a 'perfectly' waxed pair of regular classic skis, but their behavior is consistent and it's a vastly simplified solution. Instead of asking for a tiny bit more grip, skiers come up through the ranks understanding they need to learn how to ski the skis they have. And if you just can't get them working, just gotta be really good at the herringbone...

Of course there would be teething issues but that's true of any change
Just thinking out loud; again, i'm no utopian but I think it's worth throwing the ideas out there. Whether FIS or the ski federations would ever entertain something like this is another matter entirely of course.
