Also, I still believe that web-pages should be functional without JavaScript. For all of my traditional SSR / non-SPA projects I definitely put effort into ensuring my projects exhibit graceful degradation.
There's already a lot of things we can do without any scripting at all: animations and dynamic content, for example - and we can even use CSS trigger-tricks for basic interactivity (e.g. show/hide toggles) all without scripting. What I'd love to see next is something like WPF/XAML's declarative data-binding in HTML (but in a less broken way...) - and I'd like to be able to submit a <form> element directly as JSON, as well as AJAX-like <form> submissions that don't replace the current document, all without scripting - that's the dream (oh, and CSS positioning relative to an arbitrary named element, I could go on...).
I think this is actually not a tangent at all, but rather, it’s kinda the whole point! I doubt we’ll ever get to a point where there’s a single standard, because a single standard can’t satisfy everyone.
