Ryan - Implementing FB Instant Articles isn't really a plug-and-play scenario. The github repo has a disclaimer that the underlying API's are still in flux and that the plugin is still in its early stages. The program doesn't even launch until mid-April. Developers have the chance to customize the experience ahead of time - it's a plugin mostly geared towards publications with developers who are knowledgeable enough to implement it. This is a totally different demographic from folks who are using a hosted e-commerce platform.
