2) Will scope of project be to build an allocator on a simulator for

I seem to remember hearing something about a dm module that simulated SMR,
but I'm not sure. We may also be able to get some SMR disks to play
with--I'll reach out to our drive vendor friends.
Would that be https://github.com/hgst/libzbc from HGST?
Yes.
I'm not sure about a disk simulator or actual drive availability,
though.
libzbc has an emulation mode that can use files or block devices to
emulate SMR disk zones.

Just keep in mind that different vendors have different behaviors - you will
need to tweak it I assume to make it act like the drive you are interested in.
