And what happens if local flags conflict with global? |

Local wins over global |

With no warning during compilation? |

This cant be detected during compile time. At runtime the local flags are applied to flagset first and then we walk higher up the chain . Only those flags marked as persistent up the chain will be applied to current flagset only if none of their names/aliases conflict with local . It is up to the user to make sure that the conflicts dont happen. |

Release Notes
(REQUIRED)
Flags can be marked as persistent in which case they can appear in subcommands. Flags with the same name in subcommand take precedence over commands defined higher in the hierarchy. Since a flag can have multiple names/aliases it is upto the user to ensure that none of the aliases of persistent flags are defined in subcommands. Even if one of the names is matched in a subcommand none of the aliases are applied to subcommand flag parsing
