Moving to QEMU 3.0 seems like a good opportunity for such a change.
I440FX is really old and does not support modern features like IOMMU.
Q35's SATA emulation is faster than pc's IDE, native PCI express hotplug
is cleaner than ACPI based one and so on...
Also the libvirt guys added very good support for the Q35 machine (thanks!).
Management software should always specify the machine type and for the
current setups, adding '-machine pc' to the command line is not such a
big deal.
In time the pc machine will fade out and we will probably stop adding
new versions at some point.
