If I had to choose right now, a safe choice would be to focus on the primary use case and implement a clean CaseInsensitiveDict without the double-dict first-saved case-preserving feature. That said, I find the TD to be fascinating and there's more work to do before making a decision.

Please be aware that the PEP author's motivation in submitting the PEP was to have a case insensitive, case preserving dict. The generalization serves to make the new datatype more useful, but if the end result doesn't satisfy the original use case of the author, I won't be surprised if he has no motivation to work on it further :).
