Basically I want to make sure there is an issue tracking > deprecating it again when we stop worrying about any Python 2/3 support. The issue is https://bugs.python.org/issue27172, but the undeprecation isn't a Python 2/3 issue, it's a "tuples, lists and dicts are really handy representations of things, and Python developers often prefer them to more structured objects" issue. The modern inspect.getfullargspec implementation is a relatively thin wrapper around inspect.signature, and the only lossy part of the output transformation is that you can't tell the difference between positional-only and positional-or-keyword parameters.
