Nick Coghlan added the comment: Right, these are in the "Don't use them in new code, but we have absolutely no plans to actually remove them" documentation-only category of deprecation warning. However, I'm converting this to a documentation enhancement request, as the documentation could make that status clearer by moving them to a separate "Legacy builtin decorator subclasses" section at the end of https://docs.python.org/3/library/abc.html Then that section can *start* with the information on simply applying the builtin decorators on top of the abc.abstractproperty() decorator, before moving on to document the available subclasses. ---------- assignee: -> docs@python components: +Documentation -Library (Lib) nosy: +docs@python stage: -> needs patch title: Deprecated abstract base class (abc) decorators do not raise DeprecationWarning -> Move deprecated abc module decorators to separate section in docs type: behavior -> enhancement _______________________________________ Python tracker <report@bugs.python.org> <http://bugs.python.org/issue28886> _______________________________________
