To be honest, I don't really care about having "the" mod or whatever; I just make the mods that I like to play. I find it anti-immersive if they don't look nice, so I try to give them a decent amount of polish even if they're just for my own use, and since they do look nice... why not share them?
But anyway. All that said, you make a good point about allowing alternate designs and new ways to play. I originally didn't want to allow freezing bacteria or eggs because it was more work for me, and it didn't seem realistic anyway... though, this is Factorio, so "realism" is always kind of a stretch. In the newest version of the mod, I've added a new technology that lets you freeze eggs and bacteria as well.
