Though, when examining the logical aspect, I suppose it's actually *lower* impact to roll-forward an unwanted rollback; either direction, of course, runs the risk of eating edits in the interim.
The builtin rollback feature is actually fail-safe in the sense that it will do nothing if there have been additional edits after the one that was to be rolled back.
Some of the JavaScript replacements may or may not share this safety feature, and "manual" rollback (by editing an old version) certainly doesn't.
