This isn't exactly an answer, but it's a bit more than a simple comment.
First off, it's not the "same" dessert. It's similar desserts that are in the same category. It's not quite as fuzzy of a category as quick breads, but I could see some people arguing that your recipe isn't a 'classic' croissant because although there's folding, there isn't the butter lamination step.
That being said, recipes are trade-offs of many different things -- ingredient and equipment availability, time, and cost are possibly the most significant considerations, even more so than taste and texture. (99% as good at 1/3 the cost can mean a better profit in the long term). Your description of the process suggests that it can be done with a stand mixer, significantly reducing the manpower required. If you have a sheeter, you don't even need a particularly skilled (and thus more costly) person for the folding.
Some people are going to stick with 'traditional' methods, because they've built their brand / reputation on it. This is going to limit what modifications / shortcuts / trade-offs that they're willing to take ... and that's not necessarily a bad thing, as it serves as a control for comparison if nothing else. And tastes differ -- some people are going to be more sensitive to acid from vinegar than others. Some will miss the browning that you lose when you have a more acidic dough.
So, a more concrete example of modifications: I make my mom's recipe for monkey bread once a year for Christmas. Being lazy, I use a stand mixer which she didn't have ... but I think it means that I kneed it for longer. We now have micro-plane graters, so I get less pith when zesting than she did. But I'm also making a triple batch, so the assembly takes longer which affects how long some rise in the pan before I bake them. I make the dough the night before and let it rise in the fridge so I'm less rushed when I make it, so I'm developing different flavors. I don't tend to keep ground cinnamon around, so I typically have to grind it fresh (and I've also been known to use ceylon as it's easier to grind). The only modifications that I've made specifically as a choice is in the shape I bake it (she did a bundt pan, I make smaller pans to give as gifts) and in avoiding browning the top too much (as I never liked it as a kid when it got dried out).
Is this the "same" monkey bread, even though I follow her recipe? I could see arguments for either one. But my cousin once said he prefers mine.
My point is that everyone judges equivalence ("same") differently, and I'd argue that the recipes both are and aren't the same depending on context.
