Yup, it's one of those threads...
PvP consistently seems to be the last thing considered with game features. If anything, features are introduced that hamper PvP in Elite. This pattern I believe is contributing to the infamous ganking "problem" so often posted on reddit or these forums. Full disclosure, I do my share of ganking. Let's go over some avenues that can bring about meaningful PvP in this game.
1) BGS: One player faction comes into conflict with another for control of stations and systems. This has great potential to drive meaningful PvP since each side has an incentive to hamper the efforts of the other. But there are some things that get in the way:
Solo / PG: Actions are just as effective in these modes compared to open, so players have no incentive to play in open if there's threat of hostile action.
Menu Logging: Allowed by FDev, reviled by the PvP community. You can de-spawn your ship in 15 seconds after getting attacked, leaving players very little time to complete an attack. With today's defensive modules and engineering, it's incredibly easy to have a ship that can survive 15 seconds of fire from fully decked out PvP ships.
Blocking: Say each group has 3 players in a wing. Wing 1 has blocked 2 members of the opposing wing already. Because of this, instancing will likely be incredibly broken, such that either the two wings don't see each other at all, or Wing 1 will only see a single member of Wing 2, while the other two members fail to instance with the rest of the players, giving Wing 1 an advantage. They can also just proceed to block any member if the opposing faction, effectively playing in PG but in open.

3) Don't communicate before interdiction otherwise you might just get blocked.
So really, if there is a ganking problem, its really due to the design of the game, and the lack of compelling options for PvP because of it. As someone who ganks, I would absolutely love to have a compelling BGS war with another player group far more than just ganking in a random high traffic system. There'd be more fun pirate interactions as well if the current situation didn't overtly hamper pirating efforts so harshly.
TLDR: PvP players are left with little to no compelling options for PvP content, resulting in increased ganking.
