Personally this is one of my most necessary mods and the one I'm most anxiously awaiting an update for. While it's true that ore no longer runs out as fast as it used it, it still runs out, and this mod always gave me the confidence that even if my ore patches run out, my factory won't completely die. Especially in Space Age, this is important because I have to leave my factory alone and just hope my resources don't run dry before I return. They haven't yet, but it would make me a lot more comfortable to have at least a little infinite ore production, and I don't want a straight infinite-ore-patch mod.
So yes, from my perspective, this mod is still vitally necessary to the point that I'm regularly checking to see if it's been updated. No rush, I can wait, but I do hope it comes at some point.
Although... infinite scrap on Fulgora doesn't makena ton of sense. I'd be content if that was left out or configurable. Especially without enemies as a resource sink, there's not a lot of need for it anyway.
