Is there sparse fieldset support?

I searched the readme, but didn't find anything on: http://jsonapi.org/format/#fetching-sparse-fieldsets

with include and sparse fieldsets, json:api has all the same features as graphql sans typing and schema generation.

Super late response. I implemented my own reducer for this, it is fully supported, if you make a reducer that can support such an operation. Thinking of how to get that into this project.
