Here what I did... Its not perfect but good for a now to delete last word. You might found it useful.

-(void) removeLastWordFromInput{
    for (int i = self.textDocumentProxy.documentContextBeforeInput.length - 1;i > 0; i--) {
        if ([self.textDocumentProxy.documentContextBeforeInput characterAtIndex:i] == ' ')
            return;

        //delete last character
        [self.textDocumentProxy deleteBackward];
    }
}

Get the last character from the documentContextBeforeInput, delete twice, and add the character as text.

If you feel this API is lacking, make sure to open a bug report and/or an enhancement report with Apple.
