The version requirement `= 0` advertised in early development stages was an unfortunate choice, as this is going to be the opt-out once the new build config validation feature will be rolled out further. Please use `~> 1.0` instead.

The conditions version `v1` is now the default, so this key can be removed.

The coroutine-style definition of noop causes a warning on Python 3.8.

way to get rid of the warning in 3.6.
