I can confirm that only the vertices remain in the imported object.

This also doesn't work in 3.0.1 and 3.1.2. Looks like it never worked.

On a side note: The exported abc files are completely empty in Houdini. Not even the vertices / points show up.

The obj exporter has no issue with exporting these edges, this seems to be an issue with the Alembic exporter.
