Here's a "natural" place where I can see this is helpful: To carry out, Gauss-Jordan like row reductions, where you'd like the first non-zero entry in a row (the so-called pivot) to be 1, I think this is very helpful.
So, I'd be **for** keeping this, perhaps in a different name, that would reflect this. Like `reduce(v)` or perhaps, `echelonize(v)` for instance.
