I think it would only be good if its used as a learning tool and not a code-writing tool, compare:
write the best code you can -> run kibit -> spend an hour reading the docs and every blog post you can find about a feature you didn't know about -> repeat
write the best code you can -> run kibit -> show off your awesome code, you're a rockstar!
I agree with you although I think that's an unlikely scenario.
kibit, so far as I understand it, is a pattern matching solution that can replace one structure with another - more idiomatic - structure. It doesn't add anything and, hence, can't actually solve your problems for you.
