Hi Jesse - in MoI untrim is built in to the regular Delete command.

To untrim, you select all the edges of a trimming boundary, and hit delete, that will remove them same as Untrim. The edges will only be removed if they are not attached to anything else.

Well, there aren't very many situations where history would come into play with this, because most of the operations that you would do with a face like this like join or booleans, don't work with history right now.

Is there some particular situation with history that you're interested in with untrim?
