I'm not sure that the width of what we consider unclassified roads will double in the next century. >> Having actual road width is always more useful than having just some >> subjective estimate whether road is too narrow or not.

Again, width is not less subjective because it is always estimated (deprecating est_width just hides this point), it is missing in most of the highways, it is changing continuously along the roads and a width of 6 meters does not say if an hgv can pass or not, it will never replace the access restriction tags.
