What are we supposed to do with things like PCI attached FPGAs and ASICs in that case? They can have host visible devices with physical resources like MMIO ranges and interrupts without those being split up neatly as PCI subfunctions - the original use case for MFD was such ASICs, there's a few PCI drivers in there now. Adding support for those into virtual bus would make it even more of a cut'n'paste of the platform bus than it already is.
