LGTM! Once this is merged, we should try to add more tests and increase the code coverage.

yup, for sure. Codecov was broken at time I was working on implementation PR, in this PR I just want to merge from feature branch, and anything else will be in a separate PR.

Another thing we need to work on - add support for explainability in RRF #874
