From reading the title, I assumed they wanted to make me handle all Errortypes explicitly. However, they just want to replace this:

  try:
    risky_operation()
  except:
    handle_any_error()

with this:

  try:
    risky_operation()
  except Exception as e:
    handle_expected_error(e)

and this will also be legal:

  try:
    risky_operation()
  except Exception as e:
    pass

... seems fine to me, but its off the table anyway.
