OP, this will happen more and more in the future.
People have said, that ED is too shallow, has too few options to play it in different ways. FD does add these options now and will do so in the future. Inevitably, some of the additions will be things you are not interested in. Others may differ.
Rergarding restricted modules: l think they are a brilliant addition to the game and we need more of them, not less! They help to define and sharpen the charakter of the ships, make them more unique and interesting - able to give us an incentive to try them out.
Remember the X-series, where Argon ships could outfit different weapons than Split ships and the SWG was a great reason to buy the Paranid 'Perseus' (and "grind" reputation with them just for this reason)? This was and is a great driving factor to proceed in the game! ED does well in "mimiking" this (in its own and unique way)!
We have some restricted modules already: Enhanced class 1/2 thrusters for the small ships, luxury modules for passenger ships ('first class' should be limited to them, too!) and now SLFs. I hope, there is more to come in the future!
Because this won't be 'niche features' for some, but broaden and vary the way to play for all of us!
