Well, I can confirm that these bugs do still exist in the XBLA version...
* Completing Speed Highway, and jumping on the pillar outside City Hall to make the gate of the nearby storefront come down
* Taking Knuckles into the sewer by jumping through a wall near the City Hall doors
* Taking Tails into Emerald Coast by standing just outside the hotel doors and flying over the hotel
* Taking Knuckles into Emerald Coast by wedging him between the barrier and the Burger Man
* Standing on the slanted ground outside of the hotel (angled down towards the beach) as Knuckles and making him moonwalk towards Twinkle Park
I'll see what else is still intact. Incidentally, on that big list of glitches, there's a point of interest to check out that they call "Unused Part Of A Level?" You have to glide across Windy Valley as Gamma and stand on the ledge above the boss battle, where you can supposedly see an unused part of the level. I assume they mean the grassy area across the chasm... which isn't special at all. Sonic usually crosses a bridge to that area before getting swept up by the tornado.
Also, is that list implying that the area of Hot Shelter reached by pulling the plug (as Big) is some sort of beta area that wasn't meant to be accessed? That's the impression I got - and that couldn't be more incorrect, because you're CLEARLY meant to fish there.
