I would just update the proposal with the first part you mentioned.
Specifically:

- Change error() to error (method rendering HTML to non-required attr
providing IWidgetInputError) -- this would be defined in IInputWidget

- Delete IWidgetInputErrorView and its one implementation

- Change widget_macros.pt to implement the appropriate error display for
the default layer

As for the validation, you can do this without subscribers, for now.
Your view class would perform the form level validation. I'm doing this
with some views now and it works. Having the settable error attr on the
widget will let you contol which error is displayed for a specific
widget.
