It will actually be like all legacy users switched to creating an linear mapping, and then either associating already allocated irq_descs with that domain or telling the domain to pre-map a specific range of irq_descs (and manage allocations). Those two use cases will be separate APIs. I don't think they should be combined (at least from my current thinking) because it depends on whether or not the irq_descs are already allocated.
