BM25 has been available for awhile so is there a reason it is becoming default soon besides it is better in certain scenarios? Have there been improvements to the implementation recently?

I went to the elastic conf last month, there is a great talk about BM25. It mentions that BM25 is more robust against common words than plain tf*idf.
