Status of 'noload' in Python 3 stdlib ? (i.e. let's try to kill this module for Python 3)

[jmuchemb]

zodbpickle has recently entered Debian. And since it forks code from Python, it led to the following discussion: https://lists.debian.org/debian-security-tracker/2018/04/msg00021.html

In particular, I discovered that https://bugs.python.org/issue6784 is fixed and if we manage to get back the noload operation in Python 3 (it existed in Python 2), we could stop forking the stdlib modules.

1. About issue 6784, there's apparently only a small difference between upstream and zodbpickle. Upstream does not have errors='bytes' (used in ZODB._compat), but I guess we can achieve the same result with:

try:
  return loads(s)
except UnicodeDecodeError:
  return loads(s, encoding='bytes')

2. What's the status 'noload' in Python 3 stdlib ? I could not find anything in bugs.python.org.
