MASSSIVE Grain of salt. Half educated guess, half bullshit.
I'm probably wrong, but I believe "ape fabric support" refers to
Nvidia's fabric manager, which is used for virtualization. Virtualization is used in virtual machines. If we wanna
really stretch this out and go all tin foil hat, then this could be for backwards compatibility. (Virtualization != emulation though) If this is for BC, then it seems like it'll be more along the lines of the Xbox One's backwards compatibility (
here) like we predicted.
