I tried it on an A9000 too and watched the LED on each of these:

  wireless-next b8e5b0ae8, x86, the series as posted
  6.18.34, Raspberry Pi 5, arm64, the same changes
  6.18 LTS, x86, the same changes

It switched off and on as asked and blinked with traffic, on firmware
20260813 and 20261016, and the LED was registered again after a USB
reauthorize. No warnings in the kernel log, and on wireless-next an
MT7921AU and an MT7922 join and pass traffic with the series loaded.

With the pin switched to a GPIO output, the A9000 joined and passed
traffic on all three.
