Folks, As I was learning how best to add native weighted statistics, coming soon, I noticed that our ROWS FROM() constructor takes only set-returning functions, gluing the outputs together side by side without a join condition of any kind. This is a handy capability, which I don't find elsewhere in our code, modulo horrible things involving WITH ORDINALITY and FULL JOIN. Did I miss something? If not, would it make sense to allow every set-returning construct inside ROWS FROM(), rather than just some of them?
