1, it is said in [scikit-learn|https://scikit-learn.org/stable/modules/naive_bayes.html#complement-naive-bayes] that 'CNB regularly outperforms MNB (often by a considerable margin) on text classification tasks.'

2, the training part of CNB is highly similar to existing MNB, so it is a easy win to support CNB.
