 Description   

MongoDB 4.4 introduces the defaultRWConcern section in serverStatus https://docs.mongodb.com/manual/reference/command/serverStatus/#defaultrwconcern

However, this does not appear to be collected in FTDC.
This information is important since the https://docs.mongodb.com/manual/reference/command/serverStatus/#mongodb-serverstatus-serverstatus.opWriteConcernCounters.insert and related statistics use the catchall of "none" for these operations. Translating "none" to majority in 5.0 could become important.

Hello Alan,

Thanks for the update, SERVER-56861 is exactly what I had in mind.
On further consideration, I believe we can work around this so we may not to backport to 4.4.
Feel free to close this.

kevin.arhelger Please see the work we've done in SERVER-56861 as part of the 5.0 release. DOCS-14550 will document the expanded 'none' section in ServerStatus. 

Can you share about the request to 4.4 backport?
