Well, the hope would be that it would allow read-write-read sql transactions, which to my understanding will never be implemented in Spanner.

Any insight into why read-write-read sql transactions will never make it into Spanner?

Not sure if "never", but from the new Spanner paper[1]:

> While we have seen comparatively little demand for this feature internally, supporting such semantics improves compatibility with other SQL systems and their ecosystems and is on our long-term radar.
