What should be done about random engines

[Fuppy]

I'm not entirely against the premise, but cog1's singulo is intensely scuffed and unfun to work with for various reasons. I wouldn't mind at the very least it be taken out in the meantime considering its many flaws without much upside. I'm okay with the nuclear engine being on rotation in cog, although I don't understand its ins and outs well enough to comment beyond that the layout seems fine to me.
