I agree, removing SDRs in such widely used and important for the community mod without warning is ridiculous. Gemgens were removed after much debate AFAIK and they were considered broken by vast majority back then which the vote in another thread shows, not so with SDRs.
Seriously, it really irritates when people call something only remotely close "WARNING! GEMGENS" and use it as an excuse to remove it from game. I feel that options should be removed from the game only if they are seriously broken.
