TL;TR: Is this library usable (and recommended) for hooks development for shell-operator? I'd appreciate any clarification to these questions: 1. What does this notice mean exactly? https://github.com/deckhouse/lib-python/blob/a121e758848387c339553309ab08fcf73bd646cb/README.md?plain=1#L7 2. Does it still apply after merging these enhancements for shell-operator here https://github.com/deckhouse/lib-python/pull/1 ?
