Well, if there are more than one or two RowExpr creators for which a
dummy set of colnames is the best we can do anyway, that might be a
reasonable answer. But I think it would encourage people to be lazy
and let the dummy colnames be used even when they can do better, so
I'd rather not take this as a first-choice solution.
