I'm not convinced the Forgotten Realms is particularly important to the long-term health of D&D. D&D managed before FR was a thing, it can manage after. And then there can be a big 7th edition revival with lots of nostalgia.The easiest thing isn't always the right thing for the long-term health of the game.
I think "homebrew" is the core D&D setting, and that always needs to be the main focus for core rules, with the occasional foray into wide range of other settings.
