Just because it happened in the past, it doesn't mean it was good. The common parlance was a mostly derogatory fashion. I remember the hubbub when they chose to publish an entire series of "Complete X" 3.5 books to update the "Sword and Fist" series of 3rd Edition books. If it was just 2 or 3 books, or if there was more time before the 3.5 update was released, it might have been ok, but the turnaround was much shorter than that. Do people not remember the how frustrated the community was that the 3rd Edition splatbooks were outdated and replaced so quickly? The impact it had on 3rd parties too?
It also spawned all the "3.75" Pathfinder and "4.5 Essentials" arguments, none of which were positive or productive. It was trash marketing with a wholly negative legacy. It belongs in the dustbin of history.
Where we are today is NOTHING like it was back then. Today the plan is compatibility to protect the purchases that were made 9 years earlier, not invalidating and replacing entire lines of books just 3 years prior. Today there is a playtest with public engagement to make sure the fans are on board.
