The xfs_imap structure is embedded into the xfs_inode, which means the size of it directly affects the inode size. Replacing the xfs_daddr_t with an xfs_agbno_t and taking the AG information from other easily available sources allows us to shrink the structure including the typical padding from 16 bytes to 8 bytes. As a side-effect the debugging check in xfs_imap() naturally now converges to a stricter variant that checks that the cluster is located inside a single AG, and not just inside the entire device.
