Here are some more use cases to guide your thinking:

        An HTML Serializer that knows which HTML elements are empty
        and generates SGML-style empty tags for them.

        A Serializer that discards markup, outputting only text.

        A wrapping Serializer that wraps inside markup only, leaving the
        Infoset unchanged.

        A PYX-format (ESIS-format) Serializer.

        A Serializer that generates LMNL syntax.

        A Serializer that generates YAML syntax.

IOW, it cannot do so without overriding whole nodes.

I like this idea, and would add:

writeStartTag, writeEndTag, writeEmptyTag, writePITarget, writePIContent,
writeProlog, writeEpilog.
