I suggest thinking of a servlet as a response builder, and, if possible, to delegate serialization of the response (output-response & friends) till after a response? value has been created. You can happily throw exceptions during the construction of the response? value; the exceptions will be handled by whatever scaffolding you're using for your web server (that is, directly handled using with-handlers of your own making that wraps the construction of the response?, or by the handler you gave as the value of #:servlet-responder in `serve/servlet`, and so on).
