It's one of those things where it doesn't affect you until it does. It's a skill level thing. I understand how arrogant that sounds, but I promise it's not intentional, it has to do with how the mechanics of boosting and flying FA Off work, especially in ships that have crappy pitch to make up for their incredible boost (FDL, mamba, krait), in those ships, boosting is pitching, boosting is changing direction, boosting is how you put yourself in a position to fire on the other guy while he cannot fire on you. For sure, the average PvEer (the HUGE majority of players, like 90% of them), will be unaffected and in fact will find this a positive change, as it will seriously curb the boost happy NPCs, but once again you're in a situation where a single special effect is so powerful (even in pve) that to run without it is to be at a significant disadvantage. That in and of itself is evidence that this is a poorly considered implementation.
example...my CZ loadout is now going to include a single large turreted rapid fire drag frag, I know my ship is faster than the enemies without boost as I have G5 dirty drag drives, so I pull up next to the NPC, and I start firing my regular guns. During this time my frag turret is emptying it's chamber every 2 seconds without me havingn to do anything, so the NPC is stuck at cruise speed (slower than my cruise speed). The NPC will not be able to get away from me, I can just follow him nonchalently at 80% throttle and let the turret do the work (it will never miss an opportunity to fire) while occasoinally firing a few PAs to speed things along if I get bored.
