Alembic Instances are Duplicates instead of References #52646

When importing alembic files, Blender creates duplicates of the geometry data instead of references. Additionally, each instance is an object instead of a dupli group which would consume far less memory?
Alembic is outputted from Houdini. pigs_packedTransforms.abc

This behaviour is exhibited by 2.79rc2.

Of course! Tomorrow when I'm back in the office I have the tools to investigate this properly.

Looking at the changelog for 2.79, Alembic Instances were never supported by Blender. I have support for this in a branch as work-in-progress, but it won't be part of 2.79.
