Just to make some points, as a guy who watched repo being designed in the office next to me: Sub modules were completely and totally unusable for Google at that point, and something was needed sooner. There is no good reason for android to change now, so they don't. Note that repo does not solve the issue of cross-repo atomic commits in any way, shape, or form, and in fact, this is the biggest complaint ;) In fact, the gerrit team (same people who produce repo) uses submodules for pseudo-atomic cross-repo commits.
