zigbee/thread support for NRF52832

Hi, I know NRF52840 support mulitprotocol BLE/Zigbee/Thread. Would NRF52832 support those as well? For cost reason, my smart home application product would really prefer NRF52832. Is there a reason why 52832 can't be used for Zigbee/thread? Or is this a future planned date to support?
