My sense is that you are on to something. The reason i say that is that a decades-old technique (though by no means primitive or out-dated) used in operating system caches (and more recently in web apps, but far less often) is a Bayesian filter. The motivation was not explicitly connected to resolving dependencies (afaik) but rather the more general problem of how to exploit prior state (last resource requested by client) to predict future, or next state (the likelihood that a given resource will be requested next). Of course, this technique can be implemented as a directed acyclic graph, or "Bayesian Network". in any event, i like your idea, and i'm not aware of the same technique having been applied to the same problem, but my knowledge of server-side web dev is below the mean.
