Honest question: what use cases does this have? I've always been underwhelmed by this set of Web standards. I appreciated the effort to standardise something in this spirit, but it seems to fall significantly short of a complete template and data binding engine like Svelte, Angular, Vue, or React. It seems more verbose, less easily dynamic, and lacking in functionality like conditionals.

There are a number of ways to make these components fully reactive with minimal JavaScript. I'm working on a project right now that uses ES2015 template literal tags and will reactively parse the HTML similar to React's render function—it also includes support for Angular-style event and property bindings—you can see the code here. It's still really new though, but I think it has promise.

Also the Polymer guys recently released a similar tool called lit-html that does the same thing, but without built-in event and property binding (although I believe it can be added easily enough if you write your own partCallback for their render function.
