Chip / Matter support (including Thread)

Following up on the nRF52840 chip mentioned earlier. There is a USB dongle with case with that chip integrated (Seeed Studio NRF52840) that could be plugged right into my Raspberry Pi 4 where I have HA running.
From the previous posts it’s not clear to me if this USB dongle will work right away today, or if we’re still talking about future support/functionality.
I could also imagine just be using the Zigbee component of it for now as bridge and then use Thread once it’s supported by HA.

Please bear with me if this should have been obvious from previous posts - I’m still relatively new to HA.
