The readme says "existing requests keep working unmodified if not using "and", "or" or "not" as query parameters". The chapter "Nested properties workaround" does not make an exception for innerJoinsLeft, so it should not change any joins if not using "and", "or" or "not" as query parameters.
It doesn't either for AddFakeLeftJoin but that is a seperate filter so it can be expected that it will not react to the query parameters of FilterLogic ("and", "or" or "not").
