Don't you want to move as much changes as possible into separate extansions module, like it is done in sql and datafusion? At least to keep it consistent.

The transaction module contains many submodules that represent actions:

├── action.rs
├── append.rs
├── mod.rs
├── rollback_to_snapshot.rs
├── snapshot.rs
├── sort_order.rs
├── update_location.rs
├── update_properties.rs
├── update_statistics.rs
└── upgrade_format_version.rs

Our module matches to this style. Rollback is a functionality that is needed not only for our purposes, it is also implemented in the iceberg-python repository, so theoretically we can do PR in the upstream and they will wonder why the new action is in the extension module.
