It is much more efficient (from a housekeeping perspective) if filesystem

How would you stripe or manage a dataset across a mix of devices with
different geometries? That would break many of the assumptions made
by filesystems today.
I would argue it's easier to let the device virtualize this mapping
and present a consistent interface, regardless of the underlying
geometry.
You must have misunderstood me. I was talking about functionality
built into the device. As far as filesystems go, filesystems
typically allocate much larger blocks than the sector size.
