Looks like it does, I can use the list of Bluetooth devices in the QAM to quick connect to Bluetooth devices, and the controller’s battery shows up in both the QAM device list and the full Bluetooth menu.

My stadia controllers don’t support BLE and can’t wake the deck, but I have a Bluetooth keyboard that can. Going to Bluetooth menu in settings and selecting the keyboard gives me an option to disable wake functionality for it.

So yeah, looks like I can uninstall all 3 Bluetooth Decky plugins I use.
