I might not have explained it properly, I'm not trying to remove barrels from the game, and there's no relation between my mods and barrels in any way.
I'm literally just using the barreling machines as a furnace-type entity that can automatically process fluids->solids and solids->fluids, without having to manually select the recipe. Using an assembling-machine type entity (like an actual assembling machine or the chemical plant that I use now) doesn't solve the problem of hiding the recipes.
As for clutter.
People like to use barreling group mod.
Although that reminds me.. I think I figured out the problem; I previously updated Solid Fluids to move the stuff into a different group to reduce bloat on the crafting menu, but totally forgot to do the same with Reverse Factory, so I guess you were right! I can technically fix this on my end
Oh... I just looked at your barreling machine, and it's still an assembling-machine type entity... this makes it unequivocally worse than this mod, which makes the machine a furnace type entity, so it just works without having to select a recipe. Any way you could, uhh.. change that?
