I wouldn't be averse to dropping the text descriptions for operators
in places where they seem obvious ... but who decides what is obvious?
Indeed, we've gotten more than one complaint in the past that some of the
geometric and JSON operators require a longer explanation than they've
got. So one of the points here was to have a format that could adapt to
that. But in this particular table I agree they're marginal.
