Yes, this is intentional: 'stream' is the raw low-level stream, 'latex' is the high-level encoded stream. The choice to which you send the output is important. Changing it likely breaks the generation of valid LaTeX.
GRPharoUtf8CodecStream or better its abstract superclass should implement #print:. I think this was discussed in the Seaside list recently and fixed, but I might be wrong.
