And I always thought that Super Saiyan 4 was a whole new entity because Goku refers to it as "This Body" so it's almost like as you say he's mastered his Super Saiyan powers and his primal state by combining them into one new unique body which is the SSJ4 and then it is implied by Bulma that Vegeta could ascend using the new body, meaning Goku could if the show would have gone on if the ratings were better, so then we could have seen a Golden version of Goku etc. They could have done so much more for that transformation, like having it as Goku's new base form or something like that.
