Well, you can drop into a driver domain model and not have a full Linux dom0 (if you don't mind fixing on a particular hardware model). But don't forget that Mirage is about modularity though -- we have a kernel module version under development too, and a baremetal rPi one. The idea is that as the number of libraries grow, it becomes easier to pick and choose the set you need for the particular deployment environment you want to build an application on (including but not exclusively a Xen unikernel).
