I don't think so. Most common case is to configure partitions on top of
a mirror. Mirroring partitions is less common. Mostly because of
hardware RAIDs being popular. You don't expect hardware RAID vendor to
mirror partitions.

For the FreeBSD an each GEOM provider can be treated as disk device.

I'm sorry, Marcel, but what you describe here has nothing to do with
reality. To be able to implement realiable mirroring you have to use
on-disk metadata. There is no way around that. You can implement
