Ah, right, I forgot about that one while I was putting it together. So

To be honest, I'm not actually very worried. I think missing a
post-revert adjustment is the main risk, but my general sense is that
there hasn't been a lot going on with color fixes outside of my recent

After pondering over it, I have a slight preference for that, too. But
I'm also happy to hear more input.
