Does formalizing rules rob them of their goodness? Absolutely yes, 100% of the time.
You want formal rules for the places your informal rules don't cover. I've never heard of, and can't imagine, a roleplaying group taking its working informal rules and imposing formality upon them.
I don't know any game designers who've successfully formalized their group's informal rules, either. My groups' informal rules have informed my game design, of course, but for none of my games have I ever just written down what we already do.
