This just moves the function declaration into the __DEV__ guard; otherwise it ends up in production builds.

Was that what you did? You can actually add that repo as an upstream to your local repo, and git cherry-pick from there.

Given the potential for divergence, I've found it's better to essentially cherry pick that way, rather than build up a "frankenrepo" and a huge .git folder.
