Simon, what do you think about this?

I'm a bit worried that this patch is quite late and breaks users like
Luite. Nevertheless, I am willing to hear arguments for merging.

We'll need to work that out when we get to that point. It largely
depends upon how confined and "safe" a change appears to be. That being
said, given how much other churn has happened for this release, I don't
think we want to be sloppy with merge discipline this time around.

Austin, what do you think?
