RMS has really performed excellently in this discussion and my favorite part of his critique must be this. What a sharp eye, to immediately identify the problem of a proposed solution! Indeed: Is it enough to justify the "complexity of documenting it"? That is an excellent question, and I leave it free for all to contemplate. Can we justify the complexity?
