  I don't like final. If I do, I don't do crazy subclassing and monkey-patching for fun but to achieve something in a restricted environment, for instance because I cannot use the latest version of the patched library.

  Python excels at this kind of code patching and introspection. Even "private" methods can be called or overwritten. That's good. Adding @final only makes it harder to deactivate this flag before applying some "runtime patch".
