I think you might be right on with "people who are already all-in on React and GraphQL". I honestly prefer writing JSX/React+GraphQL to a template language even for static content. I like that gatsby makes that an option without making an annoying SPA content site. It‘s a good reality check that this is likely a niche prefer ce.

And I also want to use headless CMSs or other data sources, in my current project a GraphQL source, which maps right in with the (very recent) schema stitching. So I think gatsby is the right choice for me, but I will carefully consider recommending it in the future. Being a VC backed company they may have more cheerleading than other open source SSGs going on.
