Technically it’s just a bunch of metal and other stuff but the thought of deorbiting the ISS makes me sad.

That sounds like a classical OSI layer 0 problem.

I would guess that automated systems (especially jettisoning storage) would not be implemented as the gain is to low for the risk in case of a false alarm. There would always be someone reachable and awake in case of emergency to close hatches manually. Warming up the landing module could be interesting though…

I hope the expert will answer!
