Does The Villainous Ghost Have A Future?

If you’ve seen Ant-Man and the Wasp, it seems that the villainous Ghost could have a future in the Marvel Cinematic Universe.
According to ComicBook.com, Marvel Studios president, Kevin Feige, has now confirmed as much.
In an interview with Birth.Movies. Death, Feige said:
It varies. In this case, the story was always – spoiler! – to keep her around. This was not the story of defeating a villain and everybody cheering. This is a different kind of villain story.
