Just thinking about having to change layout-dependent references, every time I add two sentences to the introduction, gives me a migraine. I never do anything like this in the paper itself, nor does anyone else that I'm aware of. I'm thinking of informal discussions, where I ask another mathematician about something specific in a paper.
