With an emulation in the kernel, we could make the usd "backend"
implementation configurable. So if the emulation is faster, users can select
the emulation, if the device is faster then the device.

Kind of what the crypto and raid code do as well.

I'm really interested in this work, as BTRFS relocation/balance will have
potential benefits, but we need to get it right.
