CLOUD-140680 will update mongot’s to return both the cursor with documents and also the explain object. The "older version" of mongot only returns the explain object. There is potential that mongod will query a version of mongot that will only return an explain object with no cursor. Once CLOUD-140680 is finished, the search team will be able to find out when there are no more users of the “older version” of mongot. At that time, the logic to handle the different versions can be removed.
