That's why I think it's the other way around.
Dr. Strange, as a more popular and marketable character, gets to take on certain properties and roles of Adam Warlock, and they leave Warlock out of the MCU. I'd rather it not develop that way, but Marvel has to combine and absorb characters whenever possible, because $150 million+ budgets for 2-3 2-hour movies every year doesn't allow for nearly as much character development and exploration as the Marvel Universe truly needs.
