Found a couple more messages we missed in the Evergreen logs. There may be other messages in those files that don't happen to show up in the Evergreen logs, so may be worth another look over those files.

src/mongo/db/s/config/sharding_catalog_manager_chunk_operations.cpp: 23887
src/mongo/db/s/range_deletion_util.cpp: 23774
src/mongo/db/s/move_primary_command.cpp: 23762
src/mongo/s/write_ops/batch_write_exec.cpp: 22911

The last one is puzzling - it looks to be fixed in master, but it was showing up in the display_sharding_multiversion test yesterday.
