How is webmention more complicated vs trackback? It just adds verification? Trackback lacked any spam control.
Well, the IndieWeb folks and the standards folks like more complex solutions (not saying they are bad) to a lot of the simple things that were working then and you lose some of the charm https://indieweb.org/Webmention

Send webmention, make POST request with parameters source and target. Receive webmention, verify source links to target and decide how to display. Specs often make things sound more technical than they are. (dshanske.com/t/1W5)
