I suppose this would be a pretty cool looking feature to add. There’d need to be a very enthusiastic programmer about this feature to get this implemented though as I estimate this to take quite a ton of programming work to do.
Plasmids has been suggested before.
Untrustedlife casually asked in 2019:
Do we still want plasmids?
Another thread where plasmids were mentioned:
The microbe roadmap is finished (see: Finishing the microbe stage roadmap). I’ll only allow adding things to it if it is required to polish an already planned / implemented feature or it is deemed an extremely important addition. I don’t see this feature matching either of those criteria, which is why I said that there’d need to be a very enthusiastic programmer who would champion this feature through the development process.
