Risks of running React 16.2 with Emotion 10

[postrad]

I just discovered on a project that we've been using Emotion 10 for a while, but we are still on React 16.2. Are there any known risks to this? It seems to be working fine. Thanks!

Are you sure that you are actually using React 16.2? Maybe your deps are using something like ^16.2.0 but the actual version that is installed is a more fresh one?

I'm certain that this project is still on v16.2, much to my chagrin. 😅

I'm unsure how this can work - Emotion 10 was relying on React.createContext and this has only been introduced in React 16.3.

How strange! We have a pretty dense monorepo, but I just did a deep dive to see if somehow a newer version of React had somehow gotten introduced. But we are definitely on v16.2. I appreciate the answer, though, and if I learn anything useful I will happily share it here.

I'm sorry- it turns out there isn't any mystery at all. We were on React 16.12, not 16.2. I apologize for making such an obvious mistake.
