Do things work differently now and seems everyone is doing minimal rock work with bio-media?

It's so backwards isn't it? Bioballs are no good because they don't support anaerobic bacteria - that's the stuff that lowers nitrate and phosphate when you carbon dose. It seems like porous bio medias are quite good at hosting anaerobic bacteria. Back in the day there were trickle filters that some people said reduced nitrate - now we know why.
