Yeah, that's an excellent practive, but is why I'm less worried for this feature. The docs at [1] caution about "not to remove earlier backups if they might be needed when restoring later incremental backups". Like Alvaro said, should we insist a bit more about the WAL retention part in this section of the docs, down to the last full backup?
