That's because it seems to you like some esoteric feature.
To me it seems natural with OO.

I thought about this mechanism each time I had to call a base class
method.
Lisp has it, out of the box.
May be it's not so special...

Not necessarily. Once a class is declared with chains, its
deriveratives don't really need the decorator (Python will know about
it).
And even with a decorator, what if the class has 5 methods? That's one
decorator against 5 superclass calls.

That's right.
