mullvad-relay-selector/src/relay_selector/mod.rs line 750 at r2 (raw file):

        // step.
        let mut exit_relay_query = query.clone();
        exit_relay_query.wireguard_constraints.daita = Constraint::Any;

Why is the exit relay query modified here? If it can't be modified earlier/elsewhere, please leave a comment detailing why daita is set to Constraint::Any 😊

Code quote:

        let mut exit_relay_query = query.clone();
        exit_relay_query.wireguard_constraints.daita = Constraint::Any;

        AdditionalWireguardConstraints {
            daita: value.daita.unwrap_or(false),
        }

Would it make sense to use AdditionalWireguardConstraints::default instead of specifying false? 😊

AdditionalWireguardConstraints {
    daita: value.daita.unwrap_or(AdditionalWireguardConstraints::default().daita),
}

Code quote:

        AdditionalWireguardConstraints {
            daita: value.daita.unwrap_or(false),
        }

Tip: hostname

    enable_post_quantum: bool,

Could we merge request_ephermal_peer and request_ephermal_peer_with_opts? 😄

Code quote:

pub async fn request_ephemeral_peer(
    service_address: IpAddr,
    parent_pubkey: PublicKey,
    ephemeral_pubkey: PublicKey,
    enable_post_quantum: bool,
    enable_daita: bool,
