I think that is a bad idea... Or at least one I wouldn't participate in, in any case.
Hubitat doesn't own my code, can't use my code directly without permission (when they start sharing their app/driver code, they can use mine, too. Not that they would want to ), and I think hosting it in a repository they own muddies that water more than I would prefer.
Other developers can do as they wish, though, of course.
