Why isn't TM recognizing Rhino 8 edge softening & sub-object material assignments?

When using the Datasmith plugin with Rhino 8, TM 2023 & 2024 no longer recognizes edge softening and sub-object material assignments (assignment of a material to a single surface of an object). Both of these things used to work in earlier versions. Is there any chance this ability will be reintroduced? In a similar post I found on the UE forum, the developers said it’s an issue with how TM reads modifiers in a .3dm file, and that it’s not a priority. The suggested workaround is to mesh everthing, but this is not a practical solution!! Please bring these features back, as I imagine they are critical to many Rhino users workflow.
