No. Your argument seems to be "because relying even more on DNS than we do today makes things more brittle, BAD, BAD BAD, we cannot go there." The more relevant engineering question is whether the benefits of such an approach outweigh the downsides. Sure there are downsides. But there are also real potential benefits. Some of them potentially game changers in terms of addressing real deficiencies in what we have today. It may well be that having applications be more brittle would be an acceptable cost for getting a viable multihoming approach that address the route scalability problem. (All depends on what "more brittle" really means.) But the only way to answer such questions in a productive manner is to look pretty closely at a complete architecture/solution together with experience from real implementation/usage.
