it doesn't, so please explain how size of a ship restricts anyone from adding all those modules, docking computer, DSS, super cruise assist. as every ships has more than 3 module slots to fit modules in.

all ships got ONE small slot (small ships got TWO!!), that can be used to host an advanced docking computer, allowing everyone to add such a module to their ship if they want to. without changing their existing build. and for those players, who have no problem with docking their big ships manually, can use this slot for something else, like a super cruise assist module, limpet controller, DSS, etc.
The game already have given the players all the needed options to overcome these things. it is the player choice. But some player, wants to have it all, without having to sacrifice something else. And many players, tend to optimize the fun out of most games by trying to be as efficient as possible, we can see this over and over in various game, including Elite.
