I recall reading somewhere that Bryan Garner (or some similar style luminary) recommended that superscripted smaller-font footnote numbers should be bolded so that they stand out a little bit more. I often follow this advice, styling small-superscripted footnote numbers in boldface.
2/6's Justice Perren appears to have taken this idea to heart, and then some, in this decision:
As you'll see, the footnote numbers are not only bolded, but also appear to be in the same font size as the text. You can't miss them!
We'll have to keep an eye on this practice and see if it takes hold, or is merely an anomaly...
