I believe revamping CQC to include your own ships, with relative power values to make matchmaking fair, for which the formula has yet to be determined, would make CQC more popular, giving the ability to ad-hoc join fair PvP fights and giving normal gameplay an actual goal (seeing whether ones own build holds up against other players) to strive for.
Nobody needs bullies and I argue that seal clubbing (which FD tried to mitigate using the starter district but failed to do so by shifting the bully encounter points towards close the starter bubble and the first engineers) is something FD would consider sustainable. The current options (block, pg, solo) do not work 100% (blocking still requires encountering the clubber, solo and pg do not allow you to cooperate with randoms reliably and/or without additional hoops to go through) which makes casuals still averse to open.
