Well, it seems that our opinions on legibility of visual artifacts differ. It is harder to read, a) because of coarseness of diagrams' elements and b) because of additional mental effort needed to comprehend such an artifact as a whole. This is, of course, somewhat subjective, but I hope that I'm not alone in my qualitative assessment. As for having diagrams in version control, 1) my suggested approaches also allow for that and 2) I think that diffs for text-based diagrams would pretty much not be readable and, thus, of little value.
