What replaced create_user_query() hook?

I see in Adam Brown’s hooks database, that create_user_query hook was deprecated at 2.3. However, that would have been exactly what I’m looking for. Most docs that I’ve used say “this is deprecated, use X instead.” What is the new X for this? What should I use instead?

The description is exactly what I want to do: “Applied to the query used to save a new user’s information to the database, just prior to running the query.”

But the function isn’t there anymore. What should I use instead?

Thanks.
