Bluetooth support via Bluetooth 5.0+ dongle

what is the current status of Bluetooth support on OpenWrt via USB 5.0+ dongle, e.g USB 5.2 or 5.3 dongles
I did go through

The idea was floated here

can it be used to proxy Bluetooth connection BLE <--> Wifi to another Linux machine e.g. Home Assistant? using BLE at a remote location and transmitting data over IP to HA?

What does bluez support, in the version shipping with OpenWRT ?

OpenWrt Documentation is not updated.

As for Blue, it is officially on BlueZ 5.66
