An underrated component of the Alembic Standard is layering. Making it's first appearance around H17.5 / H18.0, and more than a bit later in Maya (in a mangled state), this is a criminally under-used way of working in CG.
It is very USD-like at it's core, and is still a viable option for anyone not needing/wanting the technical overheads of USD, but wanting a better way to author data from multiple Depts/Steps non-destructively.
