Rationale for this change
Closes #51143
As storage formats standardize file-level references, Arrow needs a canonical in-memory representation to preserve these semantics across IPC streams, the C Data Interface, Arrow Flight, and language bindings. Without a canonical extension type, file fields lose their semantic metadata during serialization.
