The flag bits are simply part of the objective option, so they are always
included in the discovery message (see
https://www.rfc-editor.org/rfc/rfc8990.html#name-format-of-objective-options).
It MAY also be present in the response. It could be used for a consistency
check or used actively in Dry Run mode. (We could possibly add new flags in
future.)
