Picking a pre 1.0 language to build your product always seemed like a bad choice to me. Purely on that basis and ignoring the recent drama this seems like a reasonable idea for tech debt pay down to me.

React Native is only an application framework. Using a tool with an unstable API a level down the stack seems much worse. Foundations of sand is the phrase that springs to mind.
