The action would be nice to have since on its basis it would be quite easy to set up editing result handling actions.
Currently we have two almost identical callback action impls residing in ui-dialog/ui-form modules with impls hard to extend and re-use.
Proposal is to add a EditorCallbackAction to ui-framework module which would be usable in both dialogs and forms.

A bit more details could be found in a linked wiki-page.
