Depending on how often you'd update the bundle. If it's rarely
updated, you're most probably right, but otherwise, you'd get one
round-trip for the large bundle, and one (or two for the index) for
each modified file since then. So, if the number of modified files is
small compared to the total number of files, there should be a win.
