Yes, but one rarely looks at the entire list, since the client is expected to filter the results interactively, and that list will get narrowed down pretty quickly.

FWIW, we have the same issue with normal completion of expressions, which often returns tens of thousands of results. However, once you've typed, e.g., "fpr", it's pretty clear that you want a printf, and interactive filtering can do that pretty well.
