Is there any particular reason why the implementation of
TreeViewer/TreeEditPart is based on org.eclipse.swt.widgets.Tree and not
on org.eclipse.jface.viewers.TreeViewer?

You are not required to use GEF's TreeViewer. You can use a JFace
treeviewer for your outline if you wish.
You can also extend AbstractTreeEditPart such that it calls refreshChildren
only when the TreeItem is expanded.

The JFace treeviewer is read-only. GEF's TreeViewer is designed around Tools
and EditParts, which produce commands which change the model.
