What if you worked out how the edge cases should be handled and wrote the regression tests in JS? I think the amount of required C++ code is actually quite small.
I'm not overly excited about it, I'd rather have it in core to begin with. If the goal is to see how much adoption it gets, I don't think the results would be much different than just seeing which projects copy your gist into their code. I'd be happy to "endorse" that gist as the way to get camel case for now, at least as far as my endorsement carries any weight.
