My thinking it - most resolvers will not query _all_ of NSEC ranges and DS RRs in the root zone during single day, thus most of the AXFR content would be wasted on most of the resolvers.
I'm trying to say - for well behaved resolver implementation, I don't think mirror zone vs. RFC8198 is absolutely clear winner as you propose above.
I seem to hear that there is much garbage (= non-existing TLDs) that is hitting the roots. For those, it's more a question of negative caching, and depending on how much "random" the queries are (yet-uncached), an AXFR could easily win regarding traffic/load.
