How is will it be possible to go back? The average ecom presence usually relies heavily on JS. I haven't checked in a long time that any relevant sites work without JS. I think going back to more basic approaches could even improve user experience, as many usage patterns probably would converge and simply look and function as intended. But considering that the whole web world is so fixated to solve everything with JS seems like targeting the highest resistance target you can find. Don't get me wrong, I hate this situation and we must not have a single language that dominates everything.

I also don't believe is that enthusiasts will create a significant shift. They can surely provide the fundamentals, but if there isn't a huge mainstream impact, it will not change anything.
