No, regrettably there won’t be a major UI overhaul as part of GIMP 3, it’s very much under-the-hood improvements. From what I’ve seen, the maintainers are very open to a UI overhaul, but they don’t have the right contributors to do it in a significant way.
That said, functionality like text outlines aren’t really a UI/UX feature in the main.
