The most common response I've been getting so far is that people generally want their VMs to look close to the real thing, but not sure how valid an argument that is.
Some people feel strongly about this and seem to think that ARMv8 kernels will only work with ACPI in the future...
That is certainly a misconception that has caused a lot of trouble. We will certainly keep supporting FDT boot in ARMv8 indefinitely, and I expect that most systems will not use ACPI at all.
Furthermore, even enterprise distro kernels will boot DT based kernels assuming the h/w support is mainlined despite statements to the contrary. It is a requirement in mainline kernels that DT and ACPI support to coexist. Distros are not going to go out of their way to undo/break that. And since the boot interface is DT, you can't simply turn off DT. :)
