The following files:

• src/mongo/util/namespace_string[._]*
• src/mongo/util/database_name[._]*

are currently owned by SP, while:

• src/mongo/db/database_name[._]*
• src/mongo/db/namespace_string[._]*

are owned by CAR and belong to the same module (catalog_and_routing).

To maintain consistency, ownership of the corresponding util files should also be aligned with CAR. Ideally, these util files should eventually be relocated under the `db` directory.
