Every fluids should be able to be filled into barrels

[0Navis0]

There are few fluids like ammonia, brine, holmium solution, electrocyte... which can't be filled into barrels. Which make them impossible to be transported by belts and cargo wagons, or sent by rockets to space stations and other planets. It would be coherent and useful if all fluids could be finally filled into barrels.

The complete list of fluids whose barelling was deliberately disabled: steam, ammoniacal solution, ammonia, fluorine, holmium solution, electrolyte, litium brine, lava, molten iron, molten copper, thruster fuel, thruster oxidizer.

I imagine the reason for disabling them is so the player can engage with manufacturing chains of each planet in a more meaningful way and planets don't resemble a mining patch full of mining drills without any smelting.

I understand the logic to not be able to filled barrel with lava and molten metals, but not the other fluids. If it's intentional, the best would be to add an option in config, so ultimately the players could choose if they want it or not.

It is moddable, see FluidPrototype.auto_barrel.
And there seems to be an actual mod for it - more-barrels.

I know it can be easily modified by setting auto_barrel to true in the fluid.lua file. I just think that it would be a better solution to add options in the game config.

A checklist might be good. Personally I think, most barrels are superflues. It bloats the selection interface.
