Which, while messy, doesn’t cause operational problems to validators.

ROAs are orthogonal to DNSSEC.  Nobody in the world had DNSSEC records changed because a ROA for address space was issued.

Who do you submit your NS records to update your delegation?  The DS records go to EXACTLY the same entity.  In this case it is APNIC.

The RIR’s send blobs of RRsets to each other to handle cross region delegations like this.  They can send DS records
just as easily as they send NS records.

For a while there were two zones with misaligned NS sets, but they were "fixed" rather speedily last week.  (There's no glue in the zones.)

Of those, there are some hiccups but that is something that is best handled by addressing the individual situation.  I don't see a "Flag Day" level concern - thus my curiosity above.
