Because you might want it to serve as an initialization for an iterative optimization routine (e.g., ICA) that updates the solution in place, and which assumes a dense matrix? We could theoretically get rid of `eye` and just use `convert(Array, I)`. I like that idea except for one detail: `I` doesn't actually have a size. --Tim
