While most of your statements are true, I think it may be too much to ever include.

Things that irk me the most are:
AI in a plane truckloads faster than the enemy slows down and slowly turns, because then its so much easier for the enemy to catch up - its just baaaaaad to have a whole flight of Fw190 killed by I-16 due to this.

Bomber attacks are still generally from 6, though now they sometimes get high and dive on the bomber. Beam attacks and head ons should be in the repertoire, especially when flying a faster plane, a head on approach is easy to do.

AI is near incapable of beeing unaware of an attack carried out against them - no matter how many enemies are currently close. Their SA is almost perfect, even for rookies.

AI pilots in same flight crash into each other or you just because they TOTALLY INSANELY want to fly formation in every maneuvre - and you cannot even tell them to get lost, and stay away until you are done with the maneuvre.

Bombers sometimes switch into high gear and then behave like fighters - not too funny.

And while their shooting is beyond contempt now (lower AI grades, low deflection shots - they shoot a long burst high, correct their aim, and shoot high again, and so on...), they still occassionally have a tendency to serve 600m one shot kills.
Better AI is insanely good at high deflection shots - though when parked behind bombers they still shoot a lot of ammo in the air.
Bomber gunners get shots in the dead centre of your plane, and while they may do so more often when attacking from 6, results are more critical when attacking from other directions - as usually dead centre hits from off angle injure or kill pilot. Given a sturdy plane it is usually easier to pick up a lot of speed and go for the dead six approach, at least that gives you a good shot and you can try to take out gunners.

EDIT:
Something else that is troublesome - AI always pursues severly crippled enemies that are largely out of the fight (e. g. shot out controls/control surfaces/engine smoking/severe fuel leaks/on fire) with no regards to any other enemies present or possibly arriving soon, and often end up bogged down for only the gain of putting an already largely harmless out of position enemy out of its misery.
