As bogofilter allows the user to use RF (Robinson-Fisher) as a binary filter too, that's somewhat redundant. Another reason why this wouldn't be too useful is the RF algorithm itself, which yields extreme results for messages which are easy to classify, but rather undifferentiated ones for 'unsure' messages. If it's arduous to support non-binary algorithms properly, I wouldn't support them at all and go for the first option.
