The Server team would like to convert all commands to TypedCommand, which ensures we parse the request using the IDL, instead of ad-hoc BSON manipulation.

This is not urgent but is tech debt worth addressing.

The list of QO commands we were given is:

• Agg (mongos, mongod)
• clusterBulkWrite
• clusterFindAndModify
• clusterWrite
• Count (mongos, mongod)
• Distinct (mongos, mongod)
• Explain (mongos, mongod)
• Find (mongos, mongod)
• getMore (mongos, mongod)
• planCacheClear (mongos, mongod)
• stageDebug

However some of these are actually QE.

It will probably make sense to split this up and handle one command at a time.
