Other than the dungeon I really don't think any of those things added to game in any way that the original did not.You consider this a bad thing? This was the BEST thing! We got to a final chance to spend more time with social links, everybody got a second upgraded Persona, there was a beautiful snow setting and a beautiful song, a ski trip scenario (which unfortunately led to the dreaded bonus dungeon if you pursued it) and there was the addition of Valentine's Day!
I have 100 complaints with Persona 4 and none of them were "There's just not enough time to spend with the crew" aside from Naoto of course.
The second upgraded Persona's only make an already easy game even easier. The snow setting is very good though, although not enough for me to warrant Golden as a direct upgrade.
