Isn't isapc important to allow QEMU to old operating systems that
predate the PCI era. I do recall seeing some messages about specific
cases where you cannot use the 'pc' machine type and we suggested
used of 'isapc' instead, but can't remember the exact details..
I know that's not a typical usecase for modern cloud / data center
virt, but it is interesting for usage of QEMU as a archeology tool,
so I'm loathe to see this removed unless it is demonstrably causing
an unacceptable maint burden to keep it.
