That seems silly as well, doesn’t it? Why should I wait for all the 1030 pages and 155 MB of Matter and Interactions[1] or 1442 pages and 126 MB of Life[2] to load before I can do anything with it? (Not that a hundred meg should take that much time to load, but then you realize PDF is the moral equivalent of a bunch of gzipped JSON files pointing to each other...) It would be handy if PDFs included an index of all page sizes in a single place, but they don’t, so we need to make do with what they do include somehow.
