ComponentPlayground component removed?

Question

I'm updating my CRA+Spectacle+MDX slides setup from Spectacle 5.x to 8.x, and it looks like 8.x no longer has a <ComponentPlayground> component. I can see it back in the 5.x source, but not current. Are there any plans to re-add that? I know I can always copy-paste the old component and recreate it in my own codebase, but it would be nice to have that built in.

Background Info/Attempts

Old component implementation: https://github.com/FormidableLabs/spectacle/blob/v5.8.0/src/components/component-playground.js
