This is the kind of thing versioned machine models are good for.

For instance, for the next release define virt-9.1 and virt-9.2.
Set strict-dt in virt-9.2 and reset it in virt-9.1.

C.f. hw/arm/virt.c, where virt_machine_8_2_options invokes virt_machine_9_0_options and 
then adjusts for backward compatibility.
