Another front for improvement is USB wireless support in linux. Yes I'm hijacking this to complain but currently (almost 2022) there isn't a single 5GHz capable(802.11ac) USB dongle with in-tree drivers or support by Ubuntu afaik. Only sketchy github scripts exist. Sure, this is primarily the vendors fault and you cannot compromise security and GPL for convenience but come on.
