I fail to see how turning off stacks for anything will help anything. Even if you only remove stacks for materials and upgrades you still have the major issue of thousands of stacks upgrade modules (of all kind) filling all of our chests, I would really like to keep a mildly decent number of lockers in my ship as to not cause clutter. Also you talk about "Server Side Characters", and personally would make servers unplayable for me. I have a habit of going back and forth from servers to single player to build or mine, and what if the server goes down for a while, then what do I do till it comes back. I am not in the mood to make several characters for each server I may play on as well as my own.
