In case Netlify folks are reading: I feel like this was written by someone who lives and breathes "composable web architectures" to the point that they forgot to mention what they are, why they're interesting, and how Netlify's support for them is unique.

I think it just means that you can use different stuff together, but I'm having a hard time piecing together how that's new, and why Netlify purchased Gatsby to do this.
