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.
