I think it's just Goku's Hidden Potential showing it's first signs of being there. Toriyama said in an interview that he accidentaly started the whole supersaiyan gimmick, as he wanted to make drawing easier for the manga, so he whited out the hair. That's litteraly what he said. And then he came up with the super saiyan stuff, and so decided on the path he took against the evil emporerer of the universe, freeza.

All things considered, it would be a great end to the series. Revenge against his lost heritage, all enemies were rounded out. Vegeta had his departure as a secondairy character.

But then he got some incentive to start making more, and came up with cell, the rebirth of the old RRarmy, time travel, and suddenly it leaped from a linear story, into a madness of possibilities. Technology being the central theme...

After that came the buu saga, where they actually first intended to make Gohan the new star of the show! I'm not kidding, that's what Toriyama said in an interview! But they decided it would damage their brand, and so they turned it around again.

The Buu saga being more focused on a "magical" central theme. It had to end, because he had exhausted the ideas for deepening plot lines, but did leave a mysterious hint of more coming, by allowing Uub into the series. But until today, he actually hasn't seen any significant role in the series. (GT lacked in-depth content for Uub)

And btw, I think the original intent was exactly like you said, to show a deeper hidden potential, just that... no more...
