This is what Chroma gaming looks like:
And the purpose of the Chroma extension is to stream Chroma lighting on the live Twitch channel.
I suppose I could display ChromaLink LEDs in the Viewer. That way some lights appear even if you don’t have the ChromaSDK.
That way I could say the extension is compatible with the ChromaSDK. If the ChromaSDK is missing, at least the user will see virtual LEDs.

Anyone with Chroma hardware will already have the secure Chroma REST API installed. With the ChromaSDK, the user gets the full Chroma experience.
