Early rocket fuels and LOX

It would be nice to see the first rockets in the game using early liquid rocket fuels like ethanol or naphtha rather than hydrogen. Also, the most important distinction between a rocket engine and an air breathing engine is that the rocket engine carries its oxidizer - so it would be nice if the rocket platform also had a port for some oxidizer like LOX (liquid oxygen), which I suppose could be made in the chemical plant from gaseous oxygen similar to the liquid nitrogen recipe.

To be fair, "liquid nitrogen" just got renamed to "nitrogen canister".
I'm not 100% sure this is a good change gameplay-wise, at least not unless the devs do something like a space race DLC. Right now, the rocket is meant to be a capstone achievement using some of the most difficult resources to obtain, and with the possible exception of ethanol, hydrogen is the hardest fuel to obtain.
Also, realistically, you'd never feed a rocket with raw naphtha; RP-1 and similar kerosene rocket fuels are very highly refined products.
