How to get rid of unwanted crew members?

Hello
I have now come to the point in game when I don't want more crew members. I have a few crew members I would like to get rid of. Is there such a mechanic or are you planning on adding it?
I have seen various creative solutions on forums, killing, eating, composting, abandoning, hypersleep chambers, walking out the airlock. I would not mind the possibility to just fire a member and leaving him/her on a station somewhere.
