Object.extend does nothing but adds properties to an object : ) Element.addMethods, on the other hand, allows you to "inject" set of methods into element "definitions" (of certain type). These "injected" methods then become available on elements implicitly (in some browsers like FF, Safari, etc.) or explicitly (e.g. in IE, where an element needs to be first extended). Prototype doesn't have any predefined way of intercepting element creation (or "initialization" as you call it) as well as insertion or modification. You need to "initialize inputs" manually - attach event handlers, change style, etc.
It's possible that later versions of prototype will fire custom events before/after some methods' calls (e.g. "element:updated", "element:inserted", "element:removed").
