Yes, SERVER-39807 will remove the flag entirely.

I suppose that code block would still be executed if we set useMultipleOplogEntryFormatForTransactions=false, so perhaps its removal is dependent on removing the flag entirely?

Comment by Matthew Russotto [ 21/May/19 ]

I believe the code you're referring to is still live.  At one point the plan was to remove "prepare" from the "o" field rather than the root oplog entry (SERVER-36814), but that's no longer the case.
