NVIDIA Resizable BAR?

Is this anything that could benefit Octane rendering?

If I understand what it is and what's going on under the hood with the drivers and hardware, we may see a pretty good bump in speed to load content onto the card and possibly a render bump depending on the size of the kernel code size.
The introduction comes with the RTX 3060, but you still need to check motherboard and CPU compatibility. It looks like the Intel 10th and 11th gen CPUs and a pretty large family of motherboard chipsets will be compatibile. The drivers for the other 30x0 family cards are supposed to be rolling out this month.
I'm looking forward to seeing how this plays out over time. Being able to finally directly access all of the card's memory rather than 256MB banks is going to, at the very least, simplify programming and steaming content onto the card for rendering.
Of course, I could be completely misunderstanding what's going on with it. After all, it's been part of the PCI Express spec since the 3.0 spec was released. I'm curious why no one's done anything with it in 13 years.
