Can you help me understand what you mean by vendor lock-in and how it is different from say, developing a plugin for Wordpress vs a plugin for Ghost? Aren't you still choosing a platform? Or do you mean technology lock-in, because we built our API server in golang? For the Store, we provide a reference implementation that is open source in AngularJS 1.x, but the store could be implemented in any JS framework. We have contemplated building a competing reference implementation in ReactJS, for example.
