You’d need to build those apps/apis in a minimal and elegant way to prove it’s possible. It’s beyond conception for many.
In other words, the complete opposite of what the frameworks show. They always show a todo list, or a blog. You’ll have to come heavy with way more complex apps with simple implementations.
That would be ambitious and could change minds. I’m rooting for you guys. In fact, it might be a great re-take on CSS zen garden if you guys accepted submissions for vanilla implementations and just showcased all the ways it’s possible.
