Quite long time ago it was added to avoid open code, and now we remove it to use open coded assignments. What is the motivation for now? It was added when the flags encoding was a mess. Now that the RQF_ flags are split out things have become much simpler and we don't need to hide a simple assignment of a value to a field.
