Managed Metadata in new MS List in SharePoint

Just noticed the new change to the SharePoint lists moving to MS List. Only some of my lists were updated and some were not so I attempted to recreate a simple list with 1 managed metadata column and a couple of people columns. 

The first thing I noticed what that I couldn't paste into the Managed Metadata column in grid edit mode. The hover over suggests that these fields can only be edited in the popup form. 

Quite a limiting feature if you ask me.
