I do wish I was able to find an official style guide that made this point clear, though. Do you know of one? I couldn't find it in the Chicago guide. It's sort of explained here, though it doesn't make the detailed claims that you do. I've switched my practice mostly because my intuitions agreed with yours when I read your comments, but that could be just status quo bias and me being used to saying "The Singularity Institute" until recently.
