> read-modify-write is the canonical transactional workload. That applies to explicit transactions (anything that does an UPDATE or SELECT followed by a write in a transaction), but also things that do implicit transactions (like the example above)

Your "implicit transaction" would not be consistent even if there was no replication involved at all. Explicit db transactions exist for a reason - use them.

The point is that, in a disaggregated system, the transaction processor has less flexibility about how to route parts of the same transaction (that section is a point about internal implementation details of transaction systems).
