The whole point of this thread is discussing the why they're cloning ships appearance/ specs if the main difference is SLF capability.
Because they're building what people want; Elite has become a popularity contest and Frontier only do what they are asked or screamed at to do because anything consistent, or offering choice, must be purged at (quite literally) any cost.
Popular ships and mechanics get effort. This is why exploration has ended up being Q4 this year (going on 5 years since Alpha which is when it was already apparent it needed massive work) and the PP changes have ended up going nowhere and the missions system is just a wasteland of broken promise. Congratulations, everyone. Meanwhile; the band plays on.
It's like people are completely incapable of recognising they are the very arbiters of the outcomes they then complain, bitterly, about.
Maybe rather than obsessing about "why is frontier offering ship choice in a game about ships, where the single and only most worked bit of the game
is the ships" maybe try like anything at all that is all but abandoned and see if you can, maybe, bring that laser like vision to that conundrum.
Or, you know, ask Frontier again why they are adding ship choices to a game about flying ships where that's the key mechanic. It's all good - you do you.
lol.
