We have a rule that all strings use UCS and that UCS be interchanged by
encoding UCS text in UTF-8. Therefore it seems to me the only time
punycode should ever exist is when it's necessary to encode/decode
punycode for dns operations. Since punycode is a standard Python codec
this should be trivial, you just need to determine where you do the
encode/decode (perhaps also validating user input can be successfully
encoded).
