1. I want to be able to compare w other brands 2. I don’t want any filler at all!
If chocolate goes up in price, I’ll pay more to get the real stuff, or buy less of it. I most certainly won’t buy a bar of food wax with chocolate solids, or whatever Hershey is
Depends where you live but many brands actually indicate their content of chocolate directly on the box (70%, 80% etc... unless you buy milk chocolate.
As for not wanting any filler at all: then buy pure cocoa beans! If you buy processed food you should always assume there is some kind of "filler". And not that "fillers" are also necessary sometimes to give a proper texture to what you eat and make sure the taste is consistent from one box to another.
All dane-pgp's proposed law would change is that when they change the labels to match the new formulation, which they must do, they would have to include a change date or a version number of something like that on the new label.
Now if we could only get a "roasted-on" date requirement for coffee ...
The proposal was a lot more aggressive than that -- dane-pgp specified that the packaging must mention if the ingredients stay the same but their relative proportions change. Under current law, there is no reason to alter the labeling for such a change[1], so you'd be seeing a huge requirement for new labels that weren't formerly required.
[1] Actually, there are two. First, you might switch up the relative proportions so much that the rank order of the absolute amounts changes, which would require reprinting the ingredients list. This is really unlikely.
Second, you might end up altering the Nutrition Facts information. That would also require relabeling. I don't know how likely that is; the Nutrition Facts panel is a pretty low-resolution instrument.
Large manufacturers will be fine, there's no particular reason for society to care about their wellbeing so much.
Ridiculous proposition.
Formulations change pretty much constantly for various reasons (ingredients become more expensive, or you change suppliers, or you decide to adjust something to make the product better or cheaper or both), and adding bureaucratic friction as well as packaging redesign is completely impractical. Packaging can take several weeks if not month to produce and you would have to constantly throw them away with this kind of rule. Wasteful.
