Good news about the abxylute, found out you can pair it via Bluetooth on PC and adaptive trigger and haptics work, though depending on the game implementation for support, you may get either haptics or adaptive triggers working, not both. To get both working at the same time in compatible games you need to be wired still.
This confirms what I found with official DS controllers on PC, that wired is needed for both to work in games that support DualSense.
Those deadset on using all DS features over wireless though can get one of those PS5 USB dongles and a Pico W Raspberry Pi to enable pure PS5 controller system emulation which full wireless support for all features on PC, though both of these mods cost extra.
I'm fine with Bluetooth for regular usage in games/emulation that does not support adaptive triggers so only get the haptics and motion, then plug in the cable for those few games that do come out with Adaptive trigger support.
