What we really need is for Felicity to start working on how to SCO the old G5 drives.
How to add a Thargoid titan Drive to old FSD?
We have old AX weapons and new Enhaced AX Weapons, even if the first one are useless (exception, Sirius AX missiles), apply the same to FSD, both version with exist in future games. At least, the old FSD can be downsized for ship that don't jump (I have a cold miner cutter with 2E FSD), or have cheap options for new players (none of the D-rated FSD SCO and better are as cheap as old D-rated FSD for new players).
Buy the NEW modules, waste 1-2 hours farming mats if you don't have, and engineer a new bunch of modules with pinned blueprints, next go to any engineer with FSD knowledge for Mass Manager. Its a lot easier than a patch, FDev broke things each time they add a new mechanic for existing modules.
