From this blog(https://engineering.mercari.com/en/blog/entry/20240206-3a12bb1288/), it appears that Tortoise provides a feature that I think could be called managed HPV. It offers a way for administrators to configure and manage complex HPV policies while requiring minimal configuration from application developers (i.e., the users of HPV). BTW, I have a pet turtle and really like the pictures in the documentation.
