What about creating a decorator to call super() after/before the overrided method?
I think this is a reasonable idea, but you can do it yourself in a few lines, can't you? Are there any "gotchas" that make it hard to do correctly?
Like Sven Kunze, I'm concerned about trying to standardize in the stdlib because a single method has ambiguous semantics (before, after, "during", asynchronously, ...) and the arguments to the decorated method are restricted so people will inevitably get it wrong. Alternatively, if you specify the semantics with an argument you end up with something like Lisp's "advice" function, which is a big hairball, or multiple decorators, to disambiguate.
Personally, I don't think the explicit invocation is such a big deal to need a standardized decorator in the stdlib.
YMMV, just expressing a few ideas.
