I think it might also depend on the Gigai. I mean Rukia's allowed her to use Kido. Although, we don't know too much about Isshun's gigai; it could be custom made for him only.

Also, shouldn't Karin and Yuzu be the same case as Ichigo? I mean:

They are all half Quincy. They all have spiritual awareness (well, Yuzu's is pretty weak). And they (should) all be Full bringers.

The only thing difference that I see is that Ichigo has Shinigami powers (added the Hollow).
