I think reifying character output streams via an IWriter protocol sounds like a good idea. Are you concerned about anything in particular wrt. to introducing the IWriter protocol? If the protocol is Clojure destined we may want to consider a more specific name to distinguish it from byte oriented output streams. (ICharacterWriter? IStringWriter?)
At this pre-1.0 stage in development I'm not sure how generous a deprecation policy we should feel obligated to deliver. Opinions? In this case it seems like leaving the old protocol in place is low cost but it does need to be removed in finite time. Perhaps a few months with the compiler issuing deprecation warnings when IPrintable is used? Deprecation warnings could, via the metadata map, be extended to include the date the feature would be removed and a url with instructions on how to migrate code.
