I think the majority seems to want at least give Thaumcraft a chance while there are still proponents and opponents of hunger reworking mods. If there is no overwhelming majority, I am for dropping it. Although I am biased since I am an opponent
I never really tried Galacticraft but just from playing GT and everything it looked really odd in our modpack for me. Still curious though, so I'll stay neutral on that one.
Edit: found the adjective.
