I only looked at VueJS for about an hour, but it's my impression that Vue.js is much more of an application framework for SPAs than "rich HTML"? Quickly looking at the "getting started" guide doesn't give me the impression that it will work well if JavaScript is disabled?

What I want is just intercept some (but not all) form submissions and load the results via AJAX, and such.

You can just use DOM templates with Vue.js. Basically write your HTML the way you normally would and add the Vue.js attributes that tells Vue what to bind with. If JavaScript is disabled you just have plain HTML. It does scale up to doing a full SPA with single file components and compiled templates with Webpack.

Here's a simple form example:
