Dropping Starlink as Bloat is the right list. The IEEE 802.11 domain is certainly different than IP, so typical IP CCs don’t apply. In our L4S/NQB trials, we put LL-marked packets into the AC_VI WMM queue in the Wi-Fi network. IMO there is more work in 802.11 to focus on latency – so much focus right now is on throughput over everything else.

At least, Nokia is implementing it in its network gear (for mobile operators), so the bufferbloat problem is somehow acknowledged by industry, at least initially or partially.
