Why are discoverable modes not permitted with Whitelisting?

[Darrew]

On this question it is said: "Error code 0x3201 means BLE_ERROR_GAP_DISCOVERABLE_WITH_WHITELIST: Use of Whitelist not permitted with discoverable advertising."

Why does example ble_app_hids_mouse (SDK v12.3.0) advertise with

    adv_flags                       = BLE_GAP_ADV_FLAGS_LE_ONLY_LIMITED_DISC_MODE;

and has Whitelist

    options.ble_adv_whitelist_enabled      = true;

enabled?

BLE_GAP_ADV_FLAGS_LE_ONLY_LIMITED_DISC_MODE is used because it only advertises for a limited amount of time while waiting for a new bond. The whitelist would be disabled in this case, check the m_whitelist_temporarily_disabled flag.
