Looks like a shift from operational to general concepts (except a few that
point at other things like https and doi). With much greater complexity
everywhere, one would hope discussion isn't dominated by super basic stuff.

But with greater specialization, such terms may simply represent lowest
common denominator terminology that appears everywhere (like articles,
prepositions, conjunctions, etc) rather than actual content.
