The main difference from UPDATE is the "replace" function, which combines delete and add. This is crucial for efficient RRSIG handling.
If you re-sign a subset of the RRsets at an owner, you can't say which RRSIG records to delete (which algorithm and type-covered) without providing the complete RDATA in UPDATE syntax. So UPDATE does not give you an advantage over IXFR in this common case. MIXFR allows you to provide just the new RRSIGs, and the receiver knows they replace old RRSIGs with matching owner algorithm and type-covered.
