This seems like an odd feature, with more downsides than positives. Sure: long, messy URLs seem ugly; but, anchor tags and query parameters are often integral to display the desired state of a certain page. Anchor tags especially.<p>Also, how does it determine which parameters are critical to keep in? In the example, `ie` and `node` are retained, but `smid` is stripped. Obviously, `node` is important`, but `smid` may also be, whereas `ie` seems superfluous.
