   The syntax should be marked experimental/alpha with evolving-semantics here. The problem is that FROM ... TO has a different semantics in standard SQL, it returns all rows that were active during the time window (so it can contain rows that were inserted before the time window), instead of just the appends that happened during the window. Let's discuss it tomorrow, but we might want to come up with a way to document it that this alpha/experimental at this stage.
