infra and supra are still used extensively in legal briefs, decisions, etc., where they serve as a sort of footnote to refer the reader elsewhere in the text. "The Jones decision, infra, has been interpreted..."

Years ago I worked for the General Accounting Office as an adjudicator of claims; during much of the time I reviewed the work of others, including several people my age who were in law school at night and were, to put it frankly, somewhat full of themselves. I was constantly removing things like this from their letters to claimants, most of whom had an approximate high school education.

One guy insisted on using viz., which means more or less, "to wit", as well as infra and supra. I finally had to get in his face about it, saying some nasty things about law students and him in particular. That discussion was later referred to as the "infra dig."
