Hi Samantha,
"is marked for removal" is a standard text if object has ObsoleteState property.
I think in this case table will stay but MS will add "TableType = Temporary" property to the object in nearest future.
In fact in standard this table always used as temporary and this is just warning that you shouldn't keep records in it because they'll be deleted in some environment update.
This change doesn't affect on API so it'll stay v2.0
This is the object, seems like just property will appear:
