Making app/template.html a Svelte component

[btakita]

For posterity sake, why does app/template.html use % as a separator, instead of {}? Also, why not make app/template.html a svelte component?

To clarify, template.html is not a Svelte component, but a template file with % delimiters.

Svelte supports SSR, so it should be possible to make template.html a SSR svelte component. This would make the HTML rendering isomorphic.

In my case, I'm moving a custom koa/svelte SSR app to sapper. All of the HTML was rendered in Svelte components. However, when moving to Sapper, there's the existing template.html which is just a simple search/replace template.

I miss being able to use computed properties, helper functions, child components, etc, in the top level html template/component.
