Absolutely true in general. Based on available data, I just don't thinkstaged deprecation is the best approach for dealing with union wait.

Another oddity: Portable software already has a check for theavailability of union wait. A deprecated union wait type will stillpass the configure test, and cause deprecation warnings (possiblytreated as errors) later in the build. Direct removal does not.
