I think it was already strongly consistent within regions?
like if you had tried to read a non-existent key, then wrote to it, it might continue to appear to not exist for a minute?

After a write, you would _always_ be able to read the key you just wrote.
After an update, you could get a stale copy of the key if your subsequent read hit a different server.
Anyway I am glad to see these gaps and caveats have been closed.
