Hi, In the control-spec https://spec.torproject.org/control-spec/commands.html#add_onion or https://github.com/torproject/torspec/blob/main/control-spec.txt#L1777 The ADD_ONION 'Flag' include Hidden Service options: MaxStreamsCloseCircuit and MaxStreams, among others. We also want to use the PoWDefenses and IntroDoSDefense parameters. Is the control-spec outdated or is it not possible to set these parameters via Flag? -- ╰_╯ Ciao Marco!
