Fair enough. I'm dabbling with Svelte/Sapper myself but I'm not at a point where I could roll my own with SSR and all that. Still trying out different ways to build components, gravitating towards having a fat global.css file and keeping the components themselves as thin as possible.

>Also, Sapper doesn't seem to be in active development.

For three months or so, but I wouldn't worry about that, because just a thin layer on top of Svelte, and the maintainer is very active in the Svelte repo it seems. It may only get bumps if something breaks.
