Comment (by westonruter):

 I just came across this issue when integrating [JS
 Widgets](https://github.com/xwp/wp-js-widgets) into the widgets admin
 screen. The direction I took was analogous to what is done in the
 customizer (surprise), where if the widget is not saved yet then the
 button says “Save” as it does currently, but once the widget has been
 updated (and the `widget-updated` event triggers) then the button becomes
 `disabled` and the text changes to “Saved”. Upon making another change to
 the widget, then the button becomes enabled again and the text returns to
 “Save”. In the case of an HTTP error, then the enabled Save button just
 will never turn to Saved. If the `WP_JS_Widget` failed a validation
 constraint, then the button would remain “Save” but a validation
 notification would appear in the control.

 See [attachment:saved-button-state.png] and corresponding plugin commit:

 widgets/commit/878b422e4c911bf80ce067ddd2a77cf110a7338b
