Gensim considers the `word2vec.c` code, from the original authors of the Word2Vec paper, as canonical and seeks to match its behavior exactly, even in ways it might deviate from some interpretations of the paper.
If there's an actual benefit to be had here, Gensim could add it as an option - but would likely always default to the same CBOW behavior as in `word2vec.c` (& similarly, FastText) - rather than this 'koan' variant.
