I'm pretty sure Ichigo would have been able to stand against most SR pretty easily, he is a special war power. I think they have been using Blut all along, its just not as "new-a-concept" as when they first displayed it, I think if they survive attacks or stop them, like how Mask did against Kensei's bankai (although it may be interpreted as his "Superstar" ability but I'm using this as just an example) its kind of hinted that they may be using that, because Quilge stated an attack against a bankai is pointless without blut arterie, and yet some SR have been able to consistently damage bankai wielding shinigami, although it could be possible (slightly) that blut arterie is what is required to attack the bankai itself, maybe akin to how Haschwalth broke Tensa Zangetsu? Its still a slight mystery, I'm sure it will be elaborated upon soon. But if it is the case of it always being there, it may be like the Arrancar's hierro, they stopped talking about it quite late in the invasion of Hueco Mundo and the fake karakura town arc, but its just presumed they are using that.
