If the idea is to have devs implement each kata, wouldn't it be more effective to provide not only automated tests, but also code which should be used as a basis for each challenge?

For example, if supporting a dev tag to serve assets from the filesystem, why not include a simple webserver which embeds the contents?

This would allow aspiring gophers to go straight to the high value modification of a project rather than effectively spend most of the time writing scaffolding and tests.
