--- Comment #1 from Nick Burch <ap...@gagravarr.org> ---
I'm not sure we're going to be able to add support for this in SXSSF - shifting
rows generally requires updating all sorts of back-and-forth references, which
SXSSF wouldn't be able to do as it won't have the required objects available

It's possible that someone could do a minimal implementation that just did a
few updates on rows which were in the buffer in memory, but care would need to
be taken to ensure it cleanly throws an exception if it's asked to touch
anything outside of the buffer
