Description
In MongoDB 3.4, mongos specifies that metadata for merging should be appended to an aggregation result using the parameter fromRouter=true. In MongoDB 3.6, this is renamed to needsMerge. However, 3.6 mongod still parses fromRouter in order to understand a request from a 3.4 mongos. In MongoDB 3.8, we can remove parsing of fromRouter.
