Since PyYAML v5.1 a warning on deprecation is printed:

> YAMLLoadWarning: calling yaml.load() without Loader=... is deprecated,
> as the default Loader is unsafe. Please read https://msg.pyyaml.org/load
> for full details.

Use the `FullLoader`s suggared variant `yaml.full_load` according to the
documentation [1] if it's present. Then it's assumed that PyYAML >= v5.1 is
used.
