1. My personal preference is to ask programmers to re-provide identifiers with explicit contracts that are ideally stated and specified in a separate 'contracts.rkt' file per collects/project basis. I.e., the current world is my preference. 



2. I am not strictly opposed to your suggestion because I see value in your reasoning. If we go with re-providing the identifier with its contract, I would like to see the blame assignment shifted to the re-exporting module. This does leave us with the "Carl" question: 

 who is going to be blamed when module C imports f from A and (re-provided from) B?
